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.\n\nNative 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.\n\nKey Features\n\n\nESP32-S2 Tensilica Processor – Single-core 240 MHz with 4 MB flash and 2 MB PSRAM\n\nWi-Fi 2.4 GHz – Built-in Wi-Fi for IoT connectivity\n\nNative USB – USB keyboard/mouse HID, MIDI, serial console, and disk drive support\n\nUSB-C Connector – For programming, power, and USB device functions\n\nSTEMMA QT / Qwiic Connector – Plug-and-play I2C for sensors and accessories\n\nRGB NeoPixel LED – With controllable power pin for ultra-low-power sleep\n\n13 GPIO Pins – 10× 12-bit ADC, 1× 8-bit DAC, PWM on any pin, 5× capacitive touch\n\nTwo I2C Ports – One on breakout pads, one on STEMMA QT connector\n\nHardware UART, SPI & I2S – Full peripheral support\n\nCircuitPython & Arduino – Full support for both platforms\n\n3.3 V Regulator – AP2112 with 600 mA peak output\n\nBattery Input Pads – On the underside with diode protection for up to 6 V\n\nDeep Sleep at ~100 µA – NeoPixel power control for low-power operation\n\nSeeed Xiao Compatible – Same size and pinout with castellated pads\n\n\nAlso Consider\n\n\nQT Py ESP32-S2 with uFL Antenna Port – Same board with external antenna connector for extended range\n\nQT Py ESP32-S3 – Dual-core with Wi-Fi + BLE and native USB\n\nQT Py ESP32 Pico – Dual-core classic ESP32 with Wi-Fi + Bluetooth Classic + BLE\n\nQT Py RP2040 – Dual-core ARM with native USB (no Wi-Fi)\n\n\nIdeal For\n\nWi-Fi connected IoT projects with native USB\nCircuitPython development with wireless connectivity\nUSB HID devices (keyboards, mice, MIDI controllers)\nCompact wireless sensors with STEMMA QT accessories\nBattery-powered low-power wireless projects\n\n\n\nNote: The ESP32-S2 is single-core (not dual-core like the classic ESP32) and does not have Bluetooth support. For Bluetooth, consider the QT Py ESP32-S3 or QT Py ESP32 Pico.\n\n\nResources\n\nAdafruit QT Py ESP32-S2 Learning Guide\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3054,"title":"Default Title","sku":"AF-5325","price":25.18,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":6,"option1":"Default Title"}]}
