Adafruit ESP32-S2 Feather 4MB Flash 2MB PSRAM – STEMMA QT / Qwiic

The Adafruit ESP32-S2 Feather Board With USB type C and 4 MB flash + 2 MB of PSRAM, perfect for use with CircuitPython or Arduino with low-cost WiFi. 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 as well as some other interesting new technologies like Time of Flight distance measurements.
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
Dimensions: 52.4mm x 22.8mm x 7.2mm
