Seeed Studio XIAO ESP32 S3

The Seeed Studio XIAO ESP32S3 is a very small board (21 × 17.8 mm) with the ESP32-S3R8 (dual-core Xtensa LX7, 240 MHz), 8 MB flash, 8 MB PSRAM, Wi-Fi and Bluetooth LE 5. An external antenna with U.FL connector is included. A 3.7 V LiPo battery can be connected to the solder pads on the back (negative on the side of the USB connector) and is charged via USB-C. The board is programmed with Arduino, ESP-IDF or MicroPython.

Important: The I/O pins work with 3.3 V. Higher voltages on the pins can damage the chip.
