Adafruit Metro ESP32-S2

The Adafruit Metro ESP32-S2 combines the popular Arduino UNO shield-compatible Metro form factor with the ESP32-S2 WiFi module. Featuring native USB, 4 MB flash, and 8 MB PSRAM, this board is ideal for WiFi-connected projects using CircuitPython or Arduino — and can even act as a USB keyboard, mouse, MIDI device, or disk drive.

With a built-in LiPo battery charger, multiple power options, and a STEMMA QT connector for I2C devices, the Metro ESP32-S2 is a versatile platform for IoT projects that need shield compatibility and wireless connectivity.
