Overview
The Adafruit ESP32-C6 Feather brings WiFi 6, Bluetooth 5 LE, Zigbee, and Thread (802.15.4) connectivity to the well-loved Feather form factor. Released as open-source hardware under Creative Commons, PCB files are freely available on GitHub. It runs the ESP32-C6 RISC-V SoC at 160MHz with 4MB flash and is fully compatible with the broad ecosystem of Feather Wings and add-ons.
The board includes a STEMMA QT connector for quick plug-and-play I2C sensor integration, a built-in RGB NeoPixel for status indication, and a LiPoly JST connector with USB-C charging managed by a MAX17048 fuel gauge. A dedicated NEOPIXEL_I2C_POWER pin allows software control of peripheral power, enabling deep sleep down to approximately 17µA.
Firmware support spans CircuitPython (official board support via circuitpython.org), Arduino IDE via the Espressif board support package, MicroPython, ESPHome (via OpenThread component for Thread/Matter), and full ESP-IDF support. Note that unlike ESP32-S2/S3, the C6 does not have native USB — programming requires a USB-to-serial connection.
With 22 GPIO, 6 analog inputs, SPI, I2C, UART, and PWM, it covers all standard sensor and actuator interfacing needs. Its Thread/802.15.4 support makes it suitable for Matter device prototyping alongside WiFi 6 for direct IP connectivity.
