Adafruit ESP32-S2 Feather - 2 MB PSRAM WIFI MICROCONTROLLER

The Adafruit ESP32-S2 Feather is a powerful development board that combines WiFi connectivity, native USB, and expanded memory for modern IoT applications. Featuring the ESP32-S2 single-core 240 MHz processor with 4 MB of Flash and 2 MB of PSRAM, it’s ideal for buffering and parsing large JSON files and running advanced projects. Native USB support allows the board to act as a keyboard, mouse, MIDI device, or even a disk drive.

Built in the popular Feather form factor, it’s compatible with the extensive ecosystem of Feather Wings, while the onboard STEMMA QT connector makes I2C device integration solder-free and effortless. The board supports both USB-C and LiPoly battery power, includes onboard charging, and features a LiPoly battery monitor accessible over I2C. With optimized low-power design, deep sleep current draw can be reduced to just 30 µA, making it an excellent fit for IoT, wearables, and smart home projects.

The Feather ESP32-S2 is fully assembled and tested, and works with both Arduino and CircuitPython environments for maximum flexibility.
