Adafruit ESP32-S2 Feather - 2 MB PSRAM WIFI DEVELOPMENT BOARD

The Adafruit ESP32-S2 Feather is a powerful development platform that offers WiFi connectivity, native USB, and large memory capacity for IoT and embedded projects. The ESP32-S2 is a single-core 240 MHz processor that includes 4 MB Flash and 2 MB PSRAM — perfect for handling large JSON files and versatile applications. Native USB allows it to be used as a keyboard, mouse, MIDI device, or mass storage, for example. The Feather form factor ensures compatibility with the wide Feather Wings ecosystem, and the STEMMA QT connector makes attaching I2C devices easy without soldering. The board also features LiPoly charging via USB-C and battery charge monitoring over I2C. Powerful power-saving features enable very low consumption in deep sleep, as low as 30 µA. This makes the ESP32-S2 Feather an excellent choice for IoT, wearable, and smart home solutions. The device is delivered fully assembled and tested, and can be used in both Arduino and CircuitPython environments.
