The Adafruit ESP32-S3 Feather with STEMMA QT brings the dual-core ESP32-S3 to the Feather ecosystem with Wi-Fi, Bluetooth LE, and native USB. This version comes with 8 MB flash, 512 KB SRAM, and no PSRAM — suitable for ESP-IDF, Arduino, and lighter CircuitPython projects that don't require large memory buffers.
Native USB means it can act as a keyboard, mouse, MIDI device, or disk drive without an external USB-to-serial converter. It includes USB-C, LiPo battery charging and monitoring, a STEMMA QT port with switchable power, and a NeoPixel — all drawing approximately 100 µA in deep sleep.
