* This configuration can be used for a large set of ESP32 boards that

* use an ESP32-WROOM-32 module and simply break out all GPIOs to external
|
|
* pads without having any special hardware or interfaces on-board.
|
|
* Examples are Espressif's EPS32-DEVKIT or NodeMCU-ESP32S and a large
|
|
* number of clones.
