ESP32-S AI-Thinker Dev Board Schematics/PCB development board schematics, if anyone feels the need to fabricate their own board.
The board is of my design, and all components are currently in stock. I had the need for this one to work on my comm module. Feel free to change/whatever.
I put the latest ESP32-S, which amazingly is still in stock. SMH. It’s also got a balun for an external antenna, which is nice if you want to extend your range.
This board includes my hardware fixes to the bugs in the silicon which show when you program or startup the board, which are not included on other board, including the official adafruit, etc, or aliexpress, whatever, that’s why I needed my own design. These were recommended by espressif and were not included in the other boards floating around because they make the other board more expensive. Also unlike the other boards this one is a 4-layer with the signals locked inside l1 and l2 between top/bottom ground planes. The mcu plate is also grounded for better heat dissipation with vias.
As usual, this is for my own work so it may not fit your use cases. Caveat emptor.
