Waveshare ESP32-C6 2.16-Inch AMOLED Touch Dev Board w/ Wi-Fi 6 & BLE 5

You can develop for this board using Espressif's official ESP-IDF SDK, which provides full access to Wi-Fi 6, BLE, and Zigbee/Thread stacks. It is also compatible with the Arduino Core for ESP32 via the Arduino IDE or PlatformIO, offering a simpler library-based approach for basic sketches. For MicroPython, you'll need to flash a compatible firmware build that supports the ESP32-C6's peripherals. The USB Type-C port is used for serial communication and flashing via esptool.py.

For portable use, connect a standard 3.7V lithium-ion or lithium-polymer battery to the board's MX1.25 2-pin header. The integrated AXP2101 power management IC handles charging when USB is connected and provides stable voltages to all components. Monitor battery voltage via the PMIC's ADC. For lowest power consumption, utilize the ESP32-C6's deep sleep modes and disable the display and sensors when not in use. The board does not include a battery; you must source one separately.

The ESP32-C6 supports concurrent operation of its 2.4GHz radios, but with limitations due to shared hardware resources. You can run Wi-Fi and Bluetooth LE together typically. Using the IEEE 802.15.4 radio for Zigbee or Thread may require specific scheduling or time-slicing, as managed by Espressif's protocol stacks. For complex multi-protocol applications, refer to Espressif's application notes on coexistence to ensure stable performance and avoid RF interference.

The dual MEMS microphones are connected to the ES7210 ADC, which provides stereo or beamforming input for enhanced voice pickup and noise cancellation. They are designed for voice interaction applications like wake-word detection or voice commands. Access them via the I2S peripheral of the ESP32-C6, using drivers for the ES7210 codec. The ES8311 audio codec handles playback. In ESP-IDF, use the audio pipeline components; in Arduino, look for compatible I2S and audio library examples.
