Product description
Adafruit ESP32-S3 Feather is a development board based on the ESP32-S3 with a dual-core 240 MHz processor, WiFi, Bluetooth LE, and native USB support. This version is equipped with 4 MB flash memory and 2 MB PSRAM. Native USB allows the board to function as, for example, a keyboard, mouse, MIDI device, or USB storage device without a separate USB-to-serial converter.
The board can be powered via USB-C or a LiPo battery and features built-in battery charging. Battery voltage and charge level are monitored by the MAX17048 via I²C. A STEMMA QT connector with switchable power is provided for connecting I²C devices. The board also features Reset and DFU/BOOT0 buttons, status LEDs, a charge LED, and a NeoPixel. ESP-IDF, Arduino, and CircuitPython are supported.
