Adafruit QT Py ESP32-C3 WiFi Dev Board with STEMMA QT

What’s life without a little RISC? This miniature dev board features a RISC-V IoT microcontroller, the ESP32-C3, perfect for small projects and IoT applications. It comes with the popular STEMMA QT chainable I2C port, WiFi, Bluetooth LE, and plenty of FLASH and RAM memory.

The ESP32-C3 is a low-cost microcontroller from Espressif supporting 2.4 GHz Wi-Fi and Bluetooth Low Energy (Bluetooth LE). It includes 4MB of Flash memory, 400 KB of SRAM and built-in USB-to-Serial converter (not native USB, so no keyboard or disk drive functionality).

The chip integrates a rich set of peripherals including UART, I2C, I2S, LED PWM controller, DMA controller, TWAI controller, USB Serial/JTAG controller, temperature sensor, and ADC. It also supports SPI, Dual SPI, and Quad SPI interfaces. It is designed for simpler projects than ESP32-Sx or ESP32 classics.

Its state-of-the-art power and RF make it ideal for Internet of Things (IoT), wearable electronics, and smart home applications.
