It integrates WiFi 6 (802.11ax, 2.4GHz), Bluetooth 5 LE, and IEEE 802.15.4 — enabling Thread 1.3, Zigbee 3.0, and Matter support on a single RISC-V chip. The board exposes all 22 GPIO pins on breadboard-compatible headers (J1 and J3), includes a native USB-C port (up to 12 Mbps) for direct communication and programming, and a separate USB-C to UART bridge for flashing and serial monitoring. An addressable RGB LED on GPIO8, Boot and Reset buttons, and a J5 current measurement header round out the hardware features. With 8MB of SPI flash, hardware crypto acceleration, and native Matter/Thread/Zigbee support in ESP-IDF, this board is the go-to reference platform for Matter end-device development, Zigbee sensor nodes, and Thread mesh nodes. ## Where to Buy - [Espressif / AliExpress](https://openhardware.directory/r?to=https%3A%2F%2Fwww.espressif.com%2Fen%2Fcompany%2Fcontact%2Fbuy-a-sample&ref=openhardware.directory&product=espressif-esp32-c6-devkitc-1&source=md-export) — 10.00 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fdocs.espressif.com%2Fprojects%2Fesp-dev-kits%2Fen%2Flatest%2Fesp32c6%2Fesp32-c6-devkitc-1%2Fuser_guide.html&ref=openhardware.directory&product=espressif-esp32-c6-devkitc-1&source=md-export) - [github](https://openhardware.directory/r?to=https%3A%2F%2Fgithub.com%2Fespressif%2Fesp-dev-kits%2Ftree%2Fmaster%2Fesp32-c6-devkitc-1&ref=openhardware.directory&product=espressif-esp32-c6-devkitc-1&source=md-export) - [schematics](https://openhardware.directory/r?to=https%3A%2F%2Fdl.espressif.com%2Fdl%2Fschematics%2Fesp32-c6-devkitc-1-schematics_v1.4.pdf&ref=openhardware.directory&product=espressif-esp32-c6-devkitc-1&source=md-export) - [datasheet](https://openhardware.directory/r?to=https%3A%2F%2Fwww.espressif.com%2Fsites%2Fdefault%2Ffiles%2Fdocumentation%2Fesp32-c6-wroom-1_wroom-1u_datasheet_en.pdf&ref=openhardware.directory&product=espressif-esp32-c6-devkitc-1&source=md-export) ## Tags `esp32-c6`, `wifi6`, `matter`, `thread`, `zigbee`, `ble`, `risc-v`, `espressif`, `devkit` ## Images ![Espressif ESP32-C6-DevKitC-1](https://nbg1.your-objectstorage.com/openhardware-directory/entities/espressif-esp32-c6-devkitc-1/57e4027f702d.png) --- [View full device page](https://openhardware.directory/devices/espressif-esp32-c6-devkitc-1)
