ESP32-S2-DevKitM-1 Development Board

The ESP32-S2-DevKitM-1 is an entry-level development board built around the ESP32-S2-MINI-1 module. It features a single-core Xtensa LX7 processor with Wi-Fi connectivity, 4MB SPI flash, and most I/O pins broken out to breadboard-friendly headers on both sides.

Powered via Micro-USB with an on-board USB-to-UART bridge (up to 3 Mbps), this board is ready for development with the ESP-IDF framework, Arduino IDE, or CircuitPython. An addressable RGB LED (WS2812) on GPIO18 is included for status indication or testing.
