## Description

The Adafruit QT Py ESP32-S2 combines Wi-Fi connectivity with native USB in the compact QT Py form factor. Built around the ESP32-S2 — a single-core 240 MHz Tensilica processor with 4 MB flash and 2 MB PSRAM — this board can act as a USB keyboard, mouse, MIDI device, or disk drive while connecting to the internet over Wi-Fi. Native USB support means it works seamlessly with CircuitPython (showing up as a USB drive for drag-and-drop code editing) and Arduino. The STEMMA QT / Qwiic connector provides plug-and-play I2C access to hundreds of sensors, and the Seeed Xiao-compatible pinout with castellated pads makes it easy to embed in custom designs. Key Features ESP32-S2 Tensilica Processor – Single-core 240 MHz with 4 MB flash and 2 MB PSRAM Wi-Fi 2.4 GHz – Built-in Wi-Fi for IoT connectivity Native USB – USB keyboard/mouse HID, MIDI, serial console, and disk drive support USB-C Connector – For programming, power, and USB device functions STEMMA QT / Qwiic Connector – Plug-and-play I2C for sensors and accessories RGB NeoPixel LED – With controllable power pin for ultra-low-power sleep 13 GPIO Pins – 10× 12-bit ADC, 1× 8-bit DAC, PWM on any pin, 5× capacitive touch Two I2C Ports – One on breakout pads, one on STEMMA QT connector Hardware UART, SPI & I2S – Full peripheral support CircuitPython & Arduino – Full support for both platforms 3.3 V Regulator – AP2112 with 600 mA peak output Battery Input Pads – On the underside with diode protection for up to 6 V Deep Sleep at ~100 µA – NeoPixel power control for low-power operation Seeed Xiao Compatible – Same size and pinout with castellated pads Also Consider QT Py ESP32-S2 with uFL Antenna Port – Same board with external antenna connector for extended range QT Py ESP32-S3 – Dual-core with Wi-Fi + BLE and native USB QT Py ESP32 Pico – Dual-core classic ESP32 with Wi-Fi + Bluetooth Classic + BLE QT Py RP2040 – Dual-core ARM with native USB (no Wi-Fi) Ideal For Wi-Fi connected IoT projects with native USB CircuitPython development with wireless connectivity USB HID devices (keyboards, mice, MIDI controllers) Compact wireless sensors with STEMMA QT accessories Battery-powered low-power wireless projects Note: The ESP32-S2 is single-core (not dual-core like the classic ESP32) and does not have Bluetooth support.
