Description The Waveshare ESP32-C6-Zero-B Mini Wi-Fi 6 Development Board is a compact Type B ESP32-C6 board based on the ESP32-C6FH8. It supports a 5-36V wide-voltage power input, Wi-Fi 6, Bluetooth 5, and IEEE 802.15.4 wireless communication for Zigbee 3.0 and Thread projects. This ESP32-C6-Zero-B without pinheader version is suitable for soldered carrier-board designs, compact AIoT nodes, Matter/Thread experiments, and wireless sensor prototypes. For industrial ESP32 control projects that need RS485 and CAN, compare it with the same-site Waveshare Industrial ESP32-S3 Control Board. Features ESP32-C6FH8 with built-in dual processors and up to 160MHz operating frequency. Built-in 320KB ROM, 512KB HP SRAM, 16KB LP SRAM, and onboard 8MB Flash. Integrated Wi-Fi 6, Bluetooth 5, and IEEE 802.15.4 for Zigbee 3.0 and Thread. Onboard ceramic antenna by default plus IPEX 4 antenna socket, selectable through GPIO7. 5-36V wide-voltage power supply for flexible embedded power designs. Onboard USB Type-C port for downloading programs and debugging. Adapts 22 GPIO pins for flexible peripheral function configuration. Castellated module design compatible with ESP32-C6-Zero pins and suitable for SMD applications.

Product List ESP32-C6-Zero-B without pinheader x1 Other Content The official overview shows how the ESP32-C6-Zero-B combines a castellated module layout, USB Type-C, wide-voltage input, and ESP32-C6 wireless capability. This SKU is the without pinheader version. The official version image helps distinguish it from the ESP32-C6-Zero-B-M version with pre-soldered headers. The ESP32-C6 platform is positioned for AIoT applications, while Wi-Fi 6, Bluetooth 5, Zigbee 3.0, and Thread support make it useful for modern wireless device development. Use the component, pinout, and dimension drawings before carrier-board layout, antenna selection, or firmware development. The package image confirms that this listing includes one ESP32-C6-Zero-B board.
