## Description

The Adafruit ESP32-S2 Feather brings Espressif's single-core ESP32-S2 to the Feather ecosystem with native USB, 2.4 GHz Wi-Fi, 4 MB flash, and 2 MB PSRAM. Native USB support means it can act as a keyboard, mouse, MIDI device, or disk drive — no separate USB-to-serial chip needed.

In deep sleep, current draw drops to approximately 80–100 µA from the LiPo connection.
