## Description

The Adafruit QT Py ESP32-C3 is a compact Wi-Fi and Bluetooth LE development board built around the Espressif ESP32-C3 — a RISC-V microcontroller designed as a modern replacement for the ESP8266. In the tiny QT Py form factor (Seeed Xiao compatible), it packs USB-C, Wi-Fi, BLE 5.0, a STEMMA QT connector, and an RGB NeoPixel into a board small enough to embed anywhere. The ESP32-C3 features a single 32-bit RISC-V core with 4 MB flash, 400 KB SRAM, and built-in USB-to-Serial (note: not native USB, so it cannot act as a keyboard or disk drive). It supports 2.4 GHz Wi-Fi and Bluetooth LE including Mesh, making it ideal for IoT projects. Program it with Arduino or MicroPython. Key Features ESP32-C3 RISC-V Core – 32-bit single-core processor with 4 MB flash and 400 KB SRAM Wi-Fi 2.4 GHz – Full Wi-Fi with TLS/SSL support for secure IoT connections Bluetooth LE 5.0 – Including Mesh support (not Bluetooth Classic) USB-C Connector – Built-in USB-to-Serial for programming and JTAG debugging STEMMA QT / Qwiic Connector – Plug-and-play I2C for sensors and accessories RGB NeoPixel LED – Built-in addressable LED 13 GPIO Pins – 11 on breakout pads; 5× 12-bit ADC, PWM on any pin, hardware UART, SPI, I2C, and I2S 3.3 V Regulator – AP2112 with 600 mA peak output Battery Input Pads – On the underside with diode protection for up to 6 V input Low Power Modes – Light sleep at ~500 µA, deep sleep at ~300 µA Reset & Boot Buttons – Reset switch and GPIO 9 boot button for ROM bootloader entry Seeed Xiao Compatible – Same size and pinout with castellated pads for surface mounting Also Consider QT Py ESP32-S2 – Native USB with CircuitPython support QT Py ESP32-S3 – Wi-Fi + BLE with native USB and 2 MB PSRAM QT Py RP2040 – Dual-core ARM with CircuitPython (no Wi-Fi) QT Py SAMD21 – ARM Cortex-M0+ with native USB and CircuitPython Ideal For Wi-Fi connected IoT sensors and controllers Bluetooth LE mesh networks Compact wireless projects with STEMMA QT sensors Battery-powered low-power applications Note: The ESP32-C3 uses a RISC-V core (not Tensilica) and has built-in USB-to-Serial — not native USB. It cannot act as a USB keyboard, MIDI device, or disk drive. It does not run CircuitPython. For native USB support, consider the QT Py ESP32-S2 or ESP32-S3.
