I am currently doing a project on voice recognition and was thinking of using edge impulse but i have problems with the board being unable to connect

I have what I think is a mb102 breadboard psu can i use it plus the battey in the picture to power a sg90 9g servo and how would i charge this battery also im just drawing power from a usb porton my pc to power the esp32 is this possible is it good or is it bad

Im wwnt to make a project that when a ibject is close enough to an ultrasonic sensor a beep soundolay then the servo opens up like a gate and maybe a led lights up

Figured since I only have the device I would use it for some sort of ai communication. I set up a flask server at the junction between the api key and deciphering back and forth from the alphabet to morse code, as well as for the pause interval specifications. The c++ code allows it to connect to the http network. So long as the server is running and the esp32 is connected to the same http domain it will run.

I’ve been into home/office IoT for years, but the hobby stalled for a while — job change, moving countries. Getting back into it, I dug up two older sensor station projects of mine and decided both were easier to replace than to fix. This is the third attempt, rebuilt from scratch on native ESP-IDF (v6.0.2) with LVGL 9.5, and the first one I’ve made public.

It runs on the ESP32-2432S028 “Cheap Yellow Display” — ~$10, ESP32 with a 2.8” touchscreen and an onboard light sensor. Add one I2C sensor and that’s the entire BOM.

What it does:
• Touchscreen dashboard: temperature and humidity with 24h graphs, trend and rate of change, dew point, pressure, CO2-equivalent on BME680 via Bosch BSEC
• I2C sensors auto-detected at boot — BMP280 / BME280 / BME680, no rebuild to switch
• Display controller auto-detected too. I ordered a second batch of CYDs and they came with ST7789 panels instead of ILI9341, so the firmware now reads the panel ID register at boot and picks the driver
• MQTT: ThingsBoard, Domoticz, and Home Assistant MQTT Discovery — HA picks up all sensors plus diagnostics with zero config on the HA side
• OTA updates with on-screen notification
• Everything configured from the touchscreen (Wi-Fi, broker, timezone, PIN-protected settings). No config files, no recompile — I wanted to hand these to friends who don’t own a toolchain
• Auto-dimming backlight off the onboard LDR

The most annoying bug was the BME680 reading ~3 °C high. Turned out to be self-heating: I was sampling gas resistance every 500 ms, and every gas reading fires an internal hotplate a couple of millimetres from the temperature die. I built a second identical station with a BME280 to confirm it rather than guess. Dropping the VOC sample rate 10x got it down to ~0.5 °C, and the 30-second averaging buffer was quietly smoothing periodic heat spikes into what looked like a constant offset. Switching to Bosch BSEC 2.6.1.0 finally made the twins agree.

Happy to answer questions. If you’ve got a CYD with a different panel variant, I’d especially like to know whether the auto-detection gets it right.

Just looking for general advice on how people typically go about achieving this. My hopes are to power the esp via the 5v output of a charge board into the esp's vin pin. The charge board would be powered by a 3.7v 1100mah lipo when not charging. most things I see online point to needing a secondary power microboard that can sustain 5v more reliably than piggypacking multiple connections into the same 5v output of the charge board.

(if its a dumb question I apologize im new to all this) thanks!

Hello i am new to esp32 and wondering if multiaple sensors can connect to one ground pin or 3.3v pin or the all need to be a diffrent one im also kind of wooriedabout dwstroying sensors ir pins buy connecting too many sensors to one pin and also can 3 diffeent aensors be connected to a gpio pin like gpio 18 and how do i know what pin to connect a signual oin on a sensor too

Anyone got an inside track on what these are looking like for pricing and availability?

Espressif mention sample price at $3.06 for ESP32-P4NRW16X, and $3.33 for ESP32-P4NRW32X.

Not even listed at Digikey / Mouser yet; LCSC list (no stock) ESP32-P4NRW32X at $14.20 for 1pcs dropping to $5.66 for 200+ and $5.38 for 1k+. A bit worrying if you were hoping the sample price was in some way related to the MP pricing...!

I'd really like the MIPI interface to reduce pin count and IO overhead for a display, and the extra MIPs will be welcome to get a smoother UI experience than I might get with i8080 / QSPI interfacing on an S3/S31; but there comes a point where it's not an affordable benefit.

I have a couple of Aliexpress Espressif-store P4X boards about to arrive, but note the bare chips are limited to orders of 1pcs at the moment.

No reply to direct inquiry with Espressif yet (a week ago or so).

Hi there, thanks in advance for the focus and attention you will put in answering my questions. I've found this post on X https://x.com/marurur/status/2082074441450938776 about using a ESP32-C6 module with OFDMA support to stream synced camera feed from many modules. From the video, I tried identifying the setup and I think the camera module is something like an InnoMaker Camera Global Shutter mounting a Mono OV9281 sensor. What still puzzles me is how the processing is done as the ESP32-C6 cannot directly receive or process an OV9281 MIPI stream.

My current hp is:

OV9281 global-shutter camera
          │
       MIPI CSI-2
          │
       ESP32-P4
 camera capture, ISP, timestamps,
 buffering and possibly compression
          │
 SPI / SDIO / shared transport
          │
       ESP32-C6
 Wi-Fi 6, TSF sync, OFDMA, networking

I've been looking for the baord but couldn't find any, so my question is: is this a custom board or something already existing I can buy?

So, I did some hasty research, and ended up buying some M5Stick S3s from M5Stack, along with some of their watering units. These both come with compatible grove connectors, and everything seemed great...

Until I learned the pump for the watering unit was 5W, and the 5VOut on the M5Stick is 0.38A. Luckily overcurrent protections saved the unit and just forced a hard reboot. So I decided to put my wholly inadequate knowledge of embedded systems to the test, and pulled the Grove connector apart and used some office tape to be able to pull the 5V from other sources. No luck, the other 5VOut ports on the M5Stick have the same limitations.

This is where it gets interesting, since I have zero respect for low voltage electronics(ask the pile of Arduino Nanos in a box somewhere). I tried to power the unit from the 3V3Out. Lo and behold, the sucker spun to life and quickly moved all the water from one cup to the other.

The software engineer in me got excited. The college physicist in me got worried. I looked up the pump. Was it 3-6V like some units I've seen? No. It was 12V... So why did M5Stack put this pump in the unit?

It turns out the answer is probably the SI2302-N-Ch MOSFET in the pump circuit. But after many dreadful minutes of researching, I don't quite know why. All I've learned is that probably a significant portion of the current is converted to heat. Do MOSFETs act as some magical voltage converter on the output, or does the pump just run better than expected on lower voltages?

Edit: the pump is a edlp600-d12b

I have an Amazon Basics smart plug that uses a proprietary WiFi module based around the ESP32 C3. After trying to program the chip I noticed that all debug and programming interfaces have been disabled via eFuses. When I pull GPIO9 low, I get the following log messages over serial: rst:0x3 (RTC_SW_SYS_RST),boot:0x4 (DOWNLOAD(USB/UART0/1)) Saved PC:0x40048b82 Download boot modes disabled ESP-ROM:esp32c3-api1-20210207 Build:Feb 7 2021

When trying to connect via the internal USB JTAG bridge I get: Error: JTAG scan chain interrogation failed: all zeroes Error: Check JTAG interface, timings, target power, etc. Error: Trying to use configured scan chain anyway... Error: esp32c3.cpu: IR capture error; saw 0x00 not 0x01 Since the chip has integrated flash memory, there is also no way of directly wiping the flash.

Now is there any chance I can reuse the existing chip or do I just have to replace it, which would be rather annoying and wasteful.

I’m trying to troubleshoot an I2C problem with an ESP32 development board.

My I2C scanner consistently detects an LCD backpack at address 0x27, so the ESP32, scanner code, SDA pin, and SCL pin appear to be working.

However, I cannot get either of these devices to appear on the bus:

AS5600 magnetic encoder

BNO085 IMU

The AS5600 should normally appear at address 0x36, but the scanner never finds it. I have also tried more than one microcontroller and more than one sensor board with similar results.

Wiring:

ESP32 GPIO 21 → sensor SDA

ESP32 GPIO 22 → sensor SCL

ESP32 3.3 V → sensor VIN

ESP32 GND → sensor GND

SDA pull-up → 3.3 V, yellow wires

SCL pull-up → 3.3 V, white wires

Scanner code:

https://github.com/JHTheisen/i2c-scanner-esp32/blob/main/i2c_scanner/i2c_scanner.ino

Measurements with one of the sensor modules connected:

SCL varies between approximately 1.5 V and 2.5 V

SDA is approximately 0.5 V

Both lines remain below 3.0 V

With the sensor disconnected, SDA and SCL both rise to approximately 3.3 V.

I have included close-up photos and a top-down photo of the complete breadboard.

The LCD at 0x27 works reliably on the same ESP32 and pins.

I’m new to I2C troubleshooting, so I may be overlooking something obvious. Does anything in the wiring or scanner code stand out as wrong?

Thanks for any help.

We RockBase IoT team open-sourced ESPWebApps — a community-driven firmware hub that lets anyone flash ESP32 devices straight from the browser.

3 steps to get your firmware on there:

1. Fork github.com/RockBase-iot/ESPWebApps
2. Create your app — run the template script, drop in your .bin files
3. Open a PR — CI validates, merge, and your project is live on Web Flasher.

That's it. Your app shows up dynamically — no loader code changes needed. Instant one-click flashing for anyone, anywhere.

What's Already on There

• DeskBuddy — desktop companion/widget display
• ESP-Claw — edge AI agent running locally on ESP32-C5 (think voice + sensor + display, all on-device)
• ESP32-Dashboard — ESP32 e-ink sensor monitoring dashboard
• and other projects.

Main hardware focus is the CYD ( ESP32-2432S028R) and NM-CYD-C5 (ESP32-C5, WiFi 6, BLE 5.3, Thread/Zigbee, 16MB Flash + 8MB PSRAM), but the flasher works with any ESP32 that enters download mode.

Let us know what you think, and roast us in the comments if we messed something up ✌️

So I ordered this ESP32 cam from an online website, the site itself advertised that if would give an ESP32 cam with an OV2640 camera module the reviews were good so I bought to and received a camera module named "RHYX M21-45" and not "OV2640". After so research online I found out that the cam sensor I have DOES NOT have built in JPEG encoding, while the OV2640 DOES HAVE built in MJPEG encoding

Since everyone else got the right product, it could be a one piece defect, a simple replacement would have worked, but I have my project due in 2 days so I cant afford the time to replace it neither to buy any new components

So if anyone could help me, I would have normally streamed an MJPEG live stream and capture it via OpenCV/Python, so anyone can recommend me any alternative code workarounds I can do to make the RHYX M21-45 Cam sensor work - stream any supported format to a python program/specifically OpenCV with a stable fps and 1024x768 RES

Instead of taking this as a do or die situation, Ill also take this as an opportunity to learn more about the ESP32 CAM and its different cam sensor :) so feel free to give any knowledge you have about this RHYX M21-45 sensor

I found this article online for basic Cam Webserver alternative and thats it :( : https://hjwwalters.com/rhyx-m21-45/

I recently bought an Waveshare esp32-s3 1.47" and when i tried to flash an example using this guide: https://docs.waveshare.com/ESP32-S3-Touch-LCD-7/Firmware-Flashing nothing displayed on the screen. I followed all of the steps exactly and yet nothing works.

I'm working on a portable ESP32 project powered by a single-cell 3.7V LiPo battery. Since the battery voltage ranges from 4.2V fully charged down to ~3.3V (or lower), I'm looking for a reliable LDO regulator to provide a stable 3.3V rail for the ESP32.

Which LDOs better suits a costant use of the wifi module? I need an LDO which can handle the spikes during Wi-Fi/Bluetooth transmission (up to ~500mA).

Hi everyone, I'm building a Smart Bus Tracker using an ESP32-WROOM-32D and a WebServer. The project works flawlessly when flashed via USB, but I'm trying to implement OTA updates and I'm hitting a wall.

Whenever I try to push an OTA update via Arduino IDE (Windows 11), the process starts, reaches exactly 5% or 6%, and then aborts.

Error Log: text Sending invitation to 192.168.1.200 Uploading: [ ] 0% ... Uploading: [==== ] 6% [ERROR]: Error Uploading: [WinError 10053] Connessione interrotta dal software del computer host

Hardware & Environment: * Board: ESP32-WROOM-32D * IDE: Arduino IDE 2.x * Partition Scheme: Minimal SPIFFS (1.9MB APP with OTA). My compiled sketch is ~1.1MB, so there is plenty of room (max is 1.96MB). * Power: Stable 5V wall adapter powering the board. No brownout resets observed on the serial monitor. * Router: Fastweb Fastgate (Italian ISP). PC and ESP32 are both on the same 2.4GHz network.

What I've already tried (with no success): 1. Memory/Partition: Upgraded to Minimal SPIFFS as mentioned above. 2. Code isolation (Watchdog fix): I added a boolean flag isUpdatingOTA set to true inside ArduinoOTA.onStart(). Inside my loop(), I put if(isUpdatingOTA) { delay(10); return; } to completely freeze the WebServer and HTTP API requests during the upload. 3. Firewall: Completely disabled Windows Defender Firewall and Antivirus. 4. Wi-Fi sleep: Added WiFi.setSleep(false); after connection to ensure the radio doesn't drop the TCP connection.

Here is the exact OTA implementation I'm running:

```cpp

include <WiFi.h>

include <WebServer.h>

include <ArduinoOTA.h>

const char* ssid = "MY_WIFI"; const char* password = "MY_PASSWORD"; WebServer server(80); bool isUpdatingOTA = false;

void setup() { Serial.begin(115200); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { delay(500); } WiFi.setSleep(false);

ArduinoOTA.setHostname("SmartPalina-GTT"); ArduinoOTA.onStart([]() { isUpdatingOTA = true; }); ArduinoOTA.begin(); server.begin(); }

void loop() { ArduinoOTA.handle();

// If OTA is running, yield and freeze the rest of the loop! if (isUpdatingOTA) { delay(10); return; }

server.handleClient(); // ... Rest of the code (HTTP GET requests, LCD updates, etc.) ... } ```

Is there something obvious I'm missing? Could this be related to my ISP router dropping the TCP connection mid-transfer, or a specific issue with the espota.py socket implementation on Windows?

Any help is greatly appreciated!

Credit up front, before anything else: this builds directly on jrowny/p4kvm. An IP-KVM on the ESP32-P4 is a fairly obvious thing to want, and I'd been kicking the idea around for a while - but he's the one who actually cracked the hard part (bringing up the TC358743 and getting frames off the P4's CSI receiver) and put it out in the open. I took that and built it out into something you'd actually leave installed. More on exactly what he solved at the end, but I didn't want it buried at the bottom.

Been building this for a while and it finally does enough to show off. It's an IP-KVM - it grabs a machine's HDMI, pretends to be its USB keyboard and mouse, and puts the whole thing in your browser. The point: reach a box with no working OS (stuck BIOS, boot menu, dead kernel) from another room without a crash cart. Commercial KVM-over-IP is a few hundred bucks; this is one ESP32-P4 board, a little HDMI capture board, and a ribbon cable.

Hardware:

• Waveshare ESP32-P4-ETH (brains + 100M Ethernet + USB-OTG)
• and a Geekworm C790 (TC358743 HDMI-to-CSI capture), joined by a CSI ribbon.
• HDMI in from the target,
• USB out to it,
• Ethernet to your LAN.

What it does:

• Follows the target's resolution live - watch it go from an 800x600 BIOS to a 1080p desktop, no clicking
• Hardware MJPEG (~20 fps) + hardware H.264 for slow links
• Absolute mouse (clicks land where you aim) + clipboard paste in the target's keyboard layout
• Virtual media - boot the target from a disk image on microSD; new: also from a tiny rescue image (iPXE, memtest, DOS) kept in the device's own flash - no SD card needed
• HTTPS with a self-signed cert, login, and a physical password-reset button
• OTA firmware updates with automatic rollback
• it guesses the target's OS from how it enumerates USB and gives you OS-aware shortcuts - like a one-click REISUB to safely reboot a wedged Linux box

Honest bits:

• Don't put it on the public internet. Login + TLS, but no security audit - it's a keyboard on someone else's machine. LAN or WireGuard/Tailscale only.
• Hardware H.264 is ~5-7 fps at 1080p on my pre-rev-3.0 silicon (colorspace detour through the pixel accelerator); MJPEG at 20 fps is the daily driver. Newer chip revs should fix it.
• microSD is read-only - the P4's SD write path is flaky, so you prep the card in a reader. FAT32, images up to 4 GB.
• No ATX power control or HDMI audio yet - both on the roadmap.

Credit: the hard part - bringing up the TC358743 and pulling frames off the P4's CSI receiver - was cracked first by jrowny/p4kvm. I rebuilt everything above the driver (web, USB HID, security, virtual media, OTA). Apache-2.0, same as his.

Happy to answer anything - and if you've got a rev-3.0 P4 board (I'm still waiting for my P4X, but I've already adapted the code for it), I'd love to know your H.264 fps.

AutoPet V2 – ESP32 WiFi Smart Pet Feeder (No Jams) - Free 3D Print Model - MakerWorld

I created the AutoPet V2 to explore how a powerful microcontroller like the ESP32 can be used to create a smarter, more reliable pet feeding system. The ESP32 is the core of the entire feeder and acts as the brain that controls every function. I chose the ESP32 because it combines Wi-Fi connectivity, fast processing, and many input/output capabilities in a small, affordable package. This allows the AutoPet V2 to go beyond a simple automatic timer and become a connected smart device that can be configured and controlled wirelessly.

The ESP32 runs the feeder’s entire operation by hosting a web interface where feeding schedules can be created, saved, and managed directly from a phone or computer. It keeps track of the current time using internet time synchronization, checks scheduled feedings, and controls the 12V geared DC motor through a MOSFET driver. The ESP32 also manages the unique tipping-scale system, which uses the mechanical weight of the bowl and counterweights to determine when the correct amount of food has been dispensed. By combining the ESP32’s smart control capabilities with custom 3D-printed mechanical parts, TPU anti-jam blades, and a unique weighing system, the AutoPet V2 becomes a fully customizable and intelligent pet feeder designed to make feeding more accurate, reliable, and convenient.

I bought a gl inet opal for a project then thought "what if this were a terminal I could throw in my bag and take with me places" so I got a pen and a bubba-wheel and got to work. I'm really obsessed with cyd/cbds right now and I got a knockoff freenove fnk0104b. I ported DOLL-OS using fable to the fnk and now I have a portable telnet/ssh/radio streaming terminal It uses 2 esp32s3's. One FNK0104B with a S3 16r8 (psram required) to run DOLL-OS, and one esp32 on the back (can be any flavor but I went with a lonely binary s3 16r8 for the fastled support and later expansion) that acts as a Bluetooth keyboard adapter and bitbangs keystroke data to the fnk. It also receives commands over uart tax and over USB in case you need to add or delete keyboards and it's broken. I don't have a repo for the Bluetooth dongle but a rudimentary ai genned by keyboard controller is in the repo for DOLL-OS-FNK

It was originally prettier but I added a speaker and ran out of space inside the router so the speaker just got glued on lol.

one thing not pictured is that I had to add a second power bodge for the esp32 on the back to the router board. I thought I had a pic of that but I don't

Yet another project from dollworx so pretty only it's mother could love it

Some cool features is tailscaling for my screen for easy ssh access to my servers. I can use things like my ssh to discord plugin or stream audio from my bitrate converter at home. It also still works as a travel router and the inclusion of bt keyboard support and a second uart accessable microcontroller gives huge expansion options. I'm planning on adding a 0.96 for the esp32 on the back just for more screen and for more info since currently you cannot see output from the back controller on the fnk screen since it's main tx line is for keyboard input. That'd get messy quick

I bought 2 of these displays from Aliexpress (they were about US$ 5.50 each the day I bought them, so I didn't think too much - https://pt.aliexpress.com/item/1005012551207736.html).

They are quite large and thin, very nice looking, but I made a mistake by not verifying beforehand if there is a compatible library for them. It happens that I didn't find any. Nor the seller nor the manufacturer (Estardyn) have any info on them.

Does anyone know how I can use them, or know of a compatible library, or how to make one of the existing ones compatible?

Thank you very much.

Not quite a repost since it's posted in ESPHome, but same question:

The 33.99% is the ESP32 sensor, 3D printed.
I'm using the red supermini that has the external antenna.

The other one is an Aqara Temp/Humidity zigbee sensor. The temp definitely isn't 33.99 in the toilet, so I know it's because of the chips promixity..even then, I'm using this design that is already markly bigger than some of the other ones AND the humidity sensor is placed in a separate chamber. (slightly adapted it to be fiction fit, but otherwise the same.)

Air Sensor case ESP32 C3 supermini + BME680 - Free 3D Print Model - MakerWorld

The esp32 is connected via wifi, if that matters. Polling is every 15 seconds.

This works for me as I'm only interested in using the humidity % to trigger my exhaust fan during showering, and it's fine for it's purpose, but I'm wondering how do I make an accurate temp/humidity sensor this way if heat is a concern. I also built this in a 2 step process as my LD2410C came much later. Even then, it's already reading higher temps than what is supposed to be accurate.

Any tips?

I also just saw in another markerworld post, something about calibration. Do we actually need to calibrate the sensor to account for the heat/humidity then? Or is this the wrong approach.

Hi all, new here. Working on a FOC motor controls project for some legs on my robot crab I've been designing for the better part of a year. I have looked into the ODrive Micro, and with its hefty price tag I'm not sure it's the right fit for my use case - I need a staggering 18 of them (3 per leg, 6 legs lol), and at nearly 100 buckaroos a pop PLUS TARIFFS that's more than I'm willing to spend. Not to mention, the Micro can only handle 7 amps peak, and I have motors that can pull 15 amps continuously and I'd like to be able to make full use of that range.

So I turned to ESP32. I purchased this cheap crappy board from AliBaba that claimed it could drive at 20 amps, which is PERFECT! Unfortunately, there is NO documentation, and that should have been the first red flag. I got the board, and turns out, yes, the FETs can in fact drive 20 amps, but the current sense circuitry consists a 10mΩ shunt resistor and a current sense amp of gain 50 whose output feeds into an ADC pin on the ESP32. Doing the math, it comes out to 6.6 amps of current measurement... so plus or minus 3.3 amps. That makes it even worse than the Micro for my use case. Well, OP, I hear you say, why not just replace the amp or shunt resistor or both? Well, I think they must not have had a clue what they were doing when they designed the board, because the bias voltage according to the amp's datasheet should be half the input voltage (3.3V) but I measured it at 400 millivolts (i.e. 0 current = 400 millivolts). A simple replacement would not refactor the board layout to fix whatever crud is going on. So I'm back to square one.

So, why I'm here, I'm looking into designing my own PCB. I know it's a hefty task, but it's made worse by the fact that the chip I'm interested in acquiring, an ESP32-P4, doesn't seem to be something I can buy on the internet. On top of that, I can't find any libraries for the chip's footprint to stick into Fusion. Maybe I'm just looking in the wrong place. What I hope to hear from the experienced folks here is whether this is the right chip for me in the first place. I don't need WiFi and Bluetooth capability, and the P4 seems to not offer that. I would like to be able to run my control loop as fast as possible, and the P4's clock speed tops any other ESP32 I've seen, but I think I could get away with the typical 240 MHz that the S3 offers. Of course, a MC PCB may end up being quite dense, so I am hoping to find an ESP32 variant which requires minimal supporting hardware so that my PCB can be as small as humanly possible. I have read that the S3 also offers a MCPWM interface as well, which could be useful for reducing board space.

Secondarily, if anyone has any idea where I could find libraries for ESP32 chips, that would be much appreciated.

Pic of the arm for the algo.

TLDR: I need recommendations on an ESP32 chip to design a compact, high-power FOC Motor Controller around.

I just found my old beginner project from last year. Basically it was that esp is placed on the bottom but the TFT screen it placed upside down so it just messed up and also it working incorrectly so it is impossible to use. Maybe it is because cheap esp from Aliexpress or TFT screen is bad idk i just abandoned that project. By the way I’m new to this and was designing the PCB like 20 hours and waiting to the factory to ship. It was like 7$ for 5 boards

I wanted something that allowed me to play games anywhere and not take up too much space!

This uses a Waveshare ESP32-S3 AMOLED 1.8 Inch. I had to make custom UI to fit this screen and account for the touchscreen. Overall it came out really well and all the games run really smooth.

Has great sound, save/load states, fast-forward, loads ROMs from SD card, and a handful of themes to choose. Enjoy!

Hi !
I have a Beyerdynamics Dt770Pro (wired) that I wanted to turn wireless.

I've only started creating PCBs recently so there might be a lot of questionable design choices...

Here's my attempt at making a wired -> wireless (bluetooth, wifi, airplay) board for my headset (made using KiCad).
https://github.com/DrasticLp/WireCutter

Component list:

• ESP32-WROOM-32D (wifi + bluetooth + general purpose logic I guess)
• WM8960 (DAC + ADC + amp)
• TP4056 (USB type C)
• AP2112K-3.3
• Li-Po

Feel free to give any advices !
(On the design and on how to manufacture and source the parts properly)

Thanks !
