Pin description of tested ESP32 board

ESP-WROOM-32 Test Board:

After I fried my last DevKit C, I've switched to this type of test board, where you can mount directly any ESP-WROOM-32 chip on it. This way I can use the latest Espressif modules (ESP-32E)

It comes with nice features like the power button or led indicators.

I also like the GPIOs disposition better on this kind of board, while remaining small enough.

These boards are suitable for permanent use, only if vibrations doesn't occur.

(note that this board exist in various model, this is the one I use, but yours may vary.

ESP32-DevKitC:

This current version of this board is based on ESP-32D and can be recognized thanks to it's antenna, protruding at the top of the board.

Another model is around, the older and deprecated version of the DevKitC, this one has it's antenna at the same height as the rest and an older version of the chip.

I recommend you to choose the newest version of the chip if possible, but this is not mandatory.

ESP32-TTGO-LCD:

I also own this board, not much to say it's a good board with a better quality than the DevKitC, a nice color LCD but unfortunately less GPIOS.
