Waveshare ESP32-S3 2.1-Inch Capacitive Touch Round Display Development Board

The board is fully compatible with Espressif's official ESP-IDF framework, the Arduino IDE using the ESP32 core, and MicroPython. For developing graphical interfaces, you can leverage libraries like LVGL (Light and Versatile Graphics Library) which is well-supported on the ESP32-S3 platform. The USB Type-C port provides a straightforward path for serial communication and firmware uploading directly from your development environment.

The capacitive touch controller communicates via the I2C bus and supports interrupt-driven operation. You will need to connect the provided SH1.0 cables from the board's display connector to the main ESP32-S3 module's GPIO pins as defined in the pinout diagram. Example code libraries are available from Waveshare to initialize the touch controller and read touch coordinates, enabling multi-point gestures for your application's user interface.

Yes, the board can be powered via the USB Type-C port, which accepts a standard 5V input. For portable battery operation, you can use a USB power bank or connect a regulated 5V source to the appropriate pins, ensuring you stay within the voltage specifications. The ESP32-S3 chip supports various deep sleep modes, which you can program to significantly reduce current consumption when the display is off, extending battery life.

The QMI8658 is a 6-axis inertial measurement unit (IMU) combining a 3-axis accelerometer and a 3-axis gyroscope. It enables motion sensing applications such as gesture control, screen orientation detection, activity tracking, or stabilization features. You can access the sensor data via I2C, using provided driver libraries to read acceleration and angular rate values, which can be processed locally on the ESP32-S3 or transmitted wirelessly.
