Adafruit ESP32-S2 Feather - 2 MB PSRAM & STEMMA QT

The ESP32-S2 is a highly-integrated, low-power, 2.4 GHz Wi-Fi System-on-Chip (SoC) solution that now has built-in native USB so it can act like a keyboard/mouse, MIDI device, disk drive, etc! It comes with 4 MB flash and 2 MB PSRAM, but only has a single-core 240 MHz chip and no Bluetooth support. Works with Arduino or CircuitPython, has easyC/Qwiic/Stemma QT I2C connector and LiPo battery connector and charger.

Features:
- ESP32-S2 240MHz Tensilica processor - the next generation of ESP32, now with native USB so it can act like a keyboard/mouse, MIDI device, disk drive, etc!
- Mini module has FCC/CE certification and comes with 4 MByte of Flash and 2 MByte of PSRAM - you can have huge data buffers
- Power options - USB type C or Lipoly battery
- Built-in battery charging when powered over USB-C
- LiPoly battery monitor - LC709203 chip actively monitors your battery for voltage and state of charge / percentage reporting over I2C
- Reset and DFU (BOOT0) buttons to get into the ROM bootloader (which is a USB serial port so you don't need a separate cable!)
- Serial debug output pin (optional, for checking the hardware serial debug console)
- STEMMA QT connector for I2C devices, with switchable power, so you can go into low power mode.
- On/Charge/User LEDs + status NeoPixel with pin-controlled power for low power usage
- Low Power friendly! In deep sleep mode we can get down to 80~100uA of current draw from the Lipoly connection. Quiescent current is from the power regulator, ESP32-S2 chip, and Lipoly monitor. Turn off the NeoPixel and external I2C power for the lowest quiescent current draw.
- Works with Arduino or CircuitPython
