Description


There is a newer version of this board available

Version 2.0: https://easyeda.com/Miraculix200/esp32-s2-test_copy


Breadboard friendly minimal dev board for ESP32-S2 Wrover or Wroom

With MCP1825 voltage regulator (500mA)

It's my first ESP32 (only used ESP8266 before), and I didn't even have the ESP32-S2 here before I designed this PCB, but it works.

Note that IO26 is not connected, as it has been discouraged in the data sheet.

You don't need to solder the GND pad in the middle. It's just for heat dissipation, which is usually not needed.

You can flash it via FTDI board, connecting RX/TX, and pulling EN and IO0 down to GND.

Parts of the circuit were copied from https://easyeda.com/fabiano.riccardi/espressif-esp32-s2-breakout-board
