ESP32-S2 Minimal Dev Board V2

Breadboard friendly minimal breakout board for ESP32-S2 Wrover or Wroom * XC6220 voltage regulator (6V max, 1000mA max, 8uA quiescent current) for battery operation * All pins except GPIO26 * FTDI header for flashing with FTDI Basic and similar boards * Uses about 53uA in deep sleep The smaller version here draws about 26uA in deep sleep, using a different voltage regulator: [https://oshwlab.com/Miraculix200/s2-tiny](https://oshwlab.com/Miraculix200/s2-tiny) Soldering the GND pad in the middle is not necessary To flash the board you need to connect GPIO0 to GND and power the device seperately from the FTDI breakout. The 3V3 pin is not connected. Connect EN to GND or push the reset button before flashing.
