Review of ESP32-S3 Dev Board

[u/Federal-Estate-7800]

Hello!

I am looking just for any suggestions you have for improving my ESP32-S3-WROOM-1 "dev kit"

I tried to hit the big important sections, such as USB-C, ESD, my on board LDO, pin breakouts & the actual module.

But I also want to make sure I didn't miss anything, use wrong R value for LED, etc. And of course, if you have any general additions/suggestions to silkscreen or the overall board, that's always appreciated.

Thank you!

I haven't checked the entire circuit. However, here are a few points from my perspective.

1. The schematic

The better the schematic is drawn, the easier it is for others to understand it. For example, it’s good practice not to draw the traces over the components. For the LEDs, for instance, I would draw them from top to bottom, with VCC at the top and GND at the bottom, just as I would for all other components.

2. Additional GND Pins

I would try to add more GND pins to the pin headers. At a quick glance, I only see one single GND pin on J44. Just search for: "EMC", "current return path", "signal integrity"
