Waveshare ESP32-C6-WROOM-1-N8 WiFi 6 & Bluetooth 5 Dev Board

You can program it using Espressif's official ESP-IDF framework or the Arduino IDE. First, install the ESP32 board support package in Arduino IDE or set up the ESP-IDF toolchain. Connect the board via the provided USB-C cable. The onboard USB hub allows you to flash code and use the serial monitor simultaneously. Select the correct COM port and board target (e.g., ESP32-C6-DevKit) in your development environment to begin uploading sketches or applications.

The castellated module design, with solderable pads along the edges, allows you to directly solder this development board onto a custom-designed carrier PCB. This transforms the dev board into an embedded wireless module for your final product, eliminating the need for connectors and saving space. It is a production-ready feature that simplifies the transition from a prototyping board to a volume-manufactured IoT device, ensuring a reliable physical and electrical connection.

The ESP32-C6's IEEE 802.15.4 radio and WiFi/Bluetooth radio share the same 2.4GHz spectrum. While the hardware supports all protocols, they typically operate in a time-shared manner managed by the firmware. You can run a Zigbee or Thread network stack concurrently with a WiFi connection, but the software application must manage the radio time-sharing to avoid interference. The ESP-IDF provides examples for multi-protocol scenarios, but simultaneous full-duplex operation on all radios is not supported.

The CH343 and CH334 chips form a USB hub controller. This setup allows the single USB-C port to provide two distinct functions: a standard USB connection to the ESP32-C6's native USB peripheral and a separate UART serial interface for debugging and console output. This means you can program the board and have serial monitor communication active over the same cable without needing an external FTDI chip or switching connections, streamlining the development workflow.
