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? What's finishing up testing and nearly ready for fabrication? 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
  • 53.2mm x 72mm / 2" x 2.8"
  • Height (w/ barrel jack): 14.8mm / 0.6"
  • Weight: 22.5g
