Waveshare ESP32-S3 2.8-Inch Capacitive Touch Round Display Dev Board

You can program it using the Arduino IDE with the ESP32 board package installed, Espressif's official ESP-IDF framework, or MicroPython. Connect the board via the onboard USB-C port to your computer. In Arduino IDE, select 'ESP32S3 Dev Module' as the board. For LVGL examples, Waveshare typically provides sample code in their GitHub repository to get started with the round display and touch interface.

The QMI8658 is a 6-axis inertial measurement unit (IMU) combining a 3-axis accelerometer and a 3-axis gyroscope. It enables motion sensing features such as detecting board orientation, gesture recognition, step counting, or stabilizing UI elements based on movement. You can access it via the I2C bus. Refer to the QMI8658 datasheet for register maps and use existing Arduino or ESP-IDF driver libraries for integration into your project.

Yes, the board includes a battery charging management module. You can connect a single-cell Li-ion or Li-Po battery (typical 3.7V) to the designated battery connector pins. The module handles charging via the USB-C port and provides stable power to the system. Implement ESP32-S3 deep sleep modes in your firmware to significantly extend battery life, waking the device on timer, touch event, or sensor interrupt.

The capacitive touch controller communicates over the I2C interface and can generate an interrupt signal. You will need to use a compatible touch library. For LVGL, you can configure the touchpad input device callback to read coordinates. Waveshare's provided examples demonstrate the initialization sequence and how to read touch points. Ensure your I2C pins are correctly mapped in your project configuration, as the touch controller uses a specific I2C bus on the ESP32-S3.
