What's Metro shaped and has an ESP32-S2 WiFi module? What has a STEMMA QT connector for I2C devices, and a Lipoly charger circuit? That's right - its the new Adafruit Metro ESP32-S2!
With native USB and a load of PSRAM this board is perfect for use with CircuitPython or Arduino, to add low-cost WiFi while keeping shield-compatibility
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!
WROVER module has FCC/CE certification and comes with 4 MByte of Flash and 2 MByte of PSRAM - you can have huge data buffers
Lotsa power options - 6-12VDC barrel jack or USB type C or Lipoly battery
Built-in battery charging when powered over DC or USB
UNO-shape so shields can plug in
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 pins (optional, for checking the hardware serial debug console)
JTAG pads for advanced debugging access.
On/Off switch
STEMMA QT connector for I2C devices
On/Charge/User LEDs + status NeoPixel
Works with Arduino or CircuitPython
