Adafruit Metro ESP32-S2 WiFi Development Board

The Adafruit Metro ESP32-S2 is a powerful Metro-shaped development board featuring the ESP32-S2 240MHz Tensilica processor with native USB support. Ideal for IoT projects, this board includes a WROVER module with 4 MB flash memory and 2 MB PSRAM, enabling large data buffers. It supports multiple power options including a 6-12VDC barrel jack, USB Type-C, or LiPoly battery with built-in battery charging and precision monitoring via MAX17048 on I2C.

Designed for compatibility, the board adopts a UNO-shape allowing shield compatibility and features an on/off switch, reset and DFU (BOOT0) buttons, serial debug pins, JTAG pads for advanced debugging, and a STEMMA QT connector for I2C devices. The board is compatible with Arduino and CircuitPython and includes on/charge/user LEDs plus a status NeoPixel for clear status indication.
