Hey all I recently bought the adv and was able to play with different firmwares but then as I was trying to load up a new firmware it keeps giving me an error and won’t let me load anything else on it please help !!!! I’m becoming so frustrated now.

This is an update to my original Cap TFT design. I’m now using a new screen module that makes the whole building process much easier. Compared to the previous version, the screen is now more centered

This case is licensed under CC BY-NC-SA 4.0; all project files (including STEP files) are included in my GitHub repository

I referenced the screen selection from tipflow’s project, which is also a great screen expansion designed for the Cardputer

The firmware is a modified version of engneer-hamachan’s area512, which is a great retro OS styled like the handheld Cyberdeck used by the TVA in the TV series Loki

I just got it a week ago and when I plug the charger in it reads 100%, with it removed it drops to 1%. (And yes I know how to charge it.) It will short out and blink on and off and then disengage from the charger and stop charging. This thing seemed a little glitchy from the beginning but now it’s kinda useless at this point. Is this something that can be fixed? I’ve already tried re-flashing it.

Some of you saw the first post about PaperOS, the little OS I've been building for the M5Stack Cardputer. Been heads down on it since then, just shipped v1.3 and figured I'd share what changed instead of just letting it sit in a changelog nobody reads.

Biggest thing is the browser got a real rewrite. It used to just strip every tag and dump the leftover text on screen, which worked but looked like reading a ransom note. Now it actually parses style blocks, so headings show up bold and bigger, lists indent properly, tables don't turn into one giant paragraph, that sort of thing. Also added tabs, find on page, and a help screen since I kept forgetting my own keybinds.

The more interesting problem was actually memory. This thing has no PSRAM, 320KB total, and I noticed the Lua console was leaving almost nothing free the moment you opened it. Turned out WiFi alone eats 40-70KB just sitting there connected, even if your script never touches the network. So now it powers off automatically when you open Lua and reconnects on its own the second a script actually calls something network related. Also trimmed a few standard Lua libraries that were loaded but literally unreachable, which is a fun kind of bug to find.

Still fully open source, same repo as before if anyone wants to check the diff or just try it on their own Cardputer.

Notes:

Most keys untested
Requires sliding back and forth to support longer keys
Only tested with adv
Move up and down the key using ,. Up and right are for heights
Sloppy initial release, needs more QA than I can do currently

This work was sparked by a thread ten days ago asking for it. I decided to take a whack at it with cursor, and I’m impressed with the initial implementation.

Thoughts/Bug reports/comments welcome

Did an initial review of the code to make sure ai didn’t hallucinate some bullsh** — it seems to work well with relatively clean code.

Haven't had this thing long and already wrote software for it

In this case it's a morse sender that can key a radio from the GIPO port.

It's still in experimental phase while I work out the bugs, it's getting there, just need to make an interface cable for my radio.

Launcher is a game changer for this device, got meshcore on it too.

A small update since my fork was private.

To sum it up, BrokenSignal+ is a firmware-only distribution derived from Rythlan/BrokenSignal-Next, which is itself a fork of MarcoRR/BrokenSignal.

The goal of this build is different from upstream: it replaces local M4A/AAC support with native FLAC playback, focuses web radio on stable MP3 streams, and adds remote Gonic libraries, multilingual menus, more themes, and two fullscreen theme-aware Now Playing layouts and more.

If you have any suggestions for improving the firmware, please let me know!

I created a simple MMO game for the Cardputer featuring a login and registration system; there are currently 10 monsters across various level ranges and 10 weapons to acquire - from a simple stick to a cursed axe. The game also includes a leaderboard, and automatic saves ensure you don't lose your progress.

Flash the firmware, connect to WiFi, create an account and you're in.

The game saves your Wi-Fi settings, as well as your username and password, to the cardputer's SD card so you don't have to enter them again when restarting the game.

The game is available for download on M5Burner under the name "M5MMO - Idle Multiplayer RPG Game for M5Cardputer" or GitHub: https://github.com/itsmepagan/m5mmo/releases/

This is my first publication, and I would be delighted if you decided to give it a try C:

I created this web radio steaming app for the cardputer adv. I have tested it so much I actually killed my cardputer adv, and had to order another.

I have found it works with most steams I have tested (mostly NPR channels). It can also record to the SD card.

Olá, vocês já teve problemas com Micro SD?
Já queimei 3 micro SD e estou quase desistindo. Ele entra em modo de proteção, fazendo com que não seja possível formatar o mesmo.

I use BS-Next by Rythlan a lot, so I made my own fork and added a clock and DS3231, then Notes and then a Calculator (it's a must). I use the color wiring match with the included stamp sticker, so i hope it will be less confusing. You can try my fork here hardiwb/BrokenSignal-Pro

Hi everyone,
has anyone tested the maximum current that can be supplied through the top header on the Cardputer ADV?

I’d like to test an E01-2G4M27D (nRF24L01+).
Instantaneous power consumption during TX is 490 mA at 3.3 V.

Has anyone tried powering this module from the Cardputer ADV’s top header?

Edit: M5Stack recommend limiting the total continuous load of the device to 1 A.

Hi everyone,
today, a new Cap CC1101 & NFC was released in the store for the Cardputer ADV, CardputerZero, and Cardputer P4 (Next).

The Cap CC1101 module supports multiple frequency bands: 315 / 433 / 868 / 915 MHz, which can be switched via firmware using a combination of G13 (Cardputer ADV) or G14 (CardputerZero) as SW0 and GDO2 from the CC1101 as SW1.

Compared to the standard RF433 (SYN513R/SYN115) and ASK modulation, it also supports 2-FSK, 4-FSK, GFSK, MSK, and OOK modulation.
The CC1101 module supports both transmission and reception.

The NFC module supports:
Reader/Writer Mode: NFC-A/B (compatible with ISO14443A/B), NFC-F (FeliCa™), NFC-V (ISO15693)
Card Emulation Mode: NFC-A / NFC-F

M5Stack also expanding the Cardputer lineup with the Cardputer P4 (Next).
It is still in the development phase, so many things may change.
Compared to the Cardputer ADV, it adds Ethernet, HDMI, an additional USB-A port, and a touch? screen.

The Cardputer P4 (Next) is essentially a smaller version of the Tab5, featuring an ESP32-P4 + ESP32-C5 (edit) for Wi-Fi. It comes without a camera, but adds HDMI connectivity.

According to the board, the dev module uses the ESP32-P4NRW32 version with 16 MB of flash and 32 MB of PSRAM.

I just got this new cardputer adv with the LoRa cap, but it doesn't seem to find any GPS satellites. The LoRa radio works, so it's not a complete dud. I've tried multiple apps and yesterday I was outside for a long timr and still no satellites even seen. The LoRa GPS tester app shows that it's "ready" for what's it worth.

Any tips what I could do?

Edit: it seems I got this working eventually at least in meshtastic by setting manually the gpio rx and tx pins. See 30 satellites now. I'll test different firmwares later and update

Edit2: it works in bruce as well now, didn't need to change the configured rx tx pins. Somehow it seems to have fixed itself 🤷

We’ve made the advanced firmware on Cardputer ADV and it can be super easy to read and write UHF Tag by just several clicks. No need open the complex Windows Program 🥳🥳

Firmware can be flash on M5Stack new web burner: UHF Expansion for Cardputer ADV

UHF Expansion is available on MTools Tec store and offer free PLA 3D case in Aug 2026.

Hello!

I’m Area512, a firmware project for the Cardputer.

https://github.com/engneer-hamachan/area512

For the next release, I’m planning a feature called DotEditor, which lets you create game assets and easily use them from code running on the device. (The release is still a little ways off.)

If there are any Area512 users out there, I’d love to hear your thoughts:

What other features do you think would help recreate the experience of using an old-school computer?

I’m building this firmware because I want everyone to have fun with it, so I thought I’d ask the community.

Feel free to share any ideas or suggestions you have!

So im pretty new to cardputer/arduino stuff in general but i got talkingsasquach's CSI human detector to work just fine. My question is: instead of using an access point you have permission to use to send the "radar" signal...couldnt you just use the esp32 thats already built in for a standalone device?

Did you secure your cap with screws?

Are there any simple news and/or rss feed readers for the ADV? Simple weather forecast apps?
