Waveshare ESP32-C6 1.69-Inch LCD Development Board

The board is fully supported by Espressif's official ESP-IDF (IoT Development Framework), which provides the most comprehensive access to Wi-Fi 6, BLE, Zigbee, and Thread features. It is also compatible with the Arduino Core for ESP32 and MicroPython, offering a simpler entry point for makers and rapid prototyping. You can program it via the onboard USB Type-C port using standard serial flashing tools within these IDEs.

For portable use, connect a single-cell 3.7V Li-ion or Li-polymer battery to the designated battery connector pins (typically labeled BAT+ and BAT-). The board includes integrated battery charging circuitry; when USB Type-C is connected, it will charge the battery. Ensure your firmware utilizes the ESP32-C6's deep sleep modes to minimize current draw and maximize battery life, as the display and wireless radios are the primary power consumers.

Yes, the ESP32-C6's processing power and peripheral interfaces (I2C for IMU/RTC, I2S for audio codec, SPI for display) allow concurrent operation. In your firmware (ESP-IDF or Arduino), you'll initialize each sensor and peripheral on its respective bus. Be mindful of timing and potential bus contention in high-speed applications. The provided driver examples for the QMI8658 IMU and ES8311 codec will help you read motion data and capture/playback audio while updating the display.

The display uses the ST7789V2 controller via SPI. You can use the LVGL graphics library, which is highly optimized for embedded systems and has excellent ESP-IDF support, to create complex interfaces. Alternatively, use the TFT_eSPI library in Arduino. First, configure the library with the correct pin definitions for the board. Graphics are updated by writing to the display's frame buffer through SPI commands. The high-speed SPI interface and the ESP32-C6's dedicated SPI peripherals ensure smooth graphics performance.
