Adafruit QT Py ESP32-S3 WiFi Dev Board with STEMMA QT - 8 MB Flash / No PSRAM

The Adafruit QT Py ESP32-S3 WiFi Dev Board is a compact and powerful microcontroller board featuring the ESP32-S3 dual-core 240 MHz Tensilica processor with WiFi and Bluetooth LE support. Perfect for IoT projects, this board comes with built-in native USB, 8 MB flash memory, and no PSRAM. Its small size matches the Seeed Xiao form-factor and features a USB Type-C connector.

This board includes 13 GPIO pins, 10 x 12-bit analog inputs, two I2C ports including a STEMMA QT connector for easy plug-and-play sensor integration, hardware UART, SPI, I2S, capacitive touch inputs, and PWM outputs on any pin. It also offers an onboard RGB NeoPixel with power control for low power consumption, and buttons for reset and bootloader mode.

Highlights include a 3.3V regulator with 600mA peak output, light sleep current as low as 2-4mA, and deep sleep current around 70μA, making it efficient for low-power applications. The QT Py ESP32-S3 is compatible with Arduino IDE and CircuitPython, supporting various USB device types such as keyboard, mouse, MIDI, and disk drive.
