## Description

The Adafruit ESP32-S3 Feather with 4 MB Flash and 2 MB PSRAM brings the dual-core ESP32-S3 to the Feather ecosystem with Wi-Fi, Bluetooth LE, and native USB. The 2 MB PSRAM provides extra memory for large data buffers, making it well-suited for CircuitPython or projects that need fast SRAM access alongside roomier PSRAM storage. 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 in the standard Feather form factor.
