2.2 Powering the Board
The board can be powered via the USB Type-C interface or a Lithium battery.
- USB Power: Connect a USB Type-C cable to the board's USB port and to a power source (e.g., computer USB port, USB wall adapter). This also enables communication for firmware downloading.
- Lithium Battery: The board includes a battery charging management module. A Lithium battery can be connected to the dedicated battery interface located at the GPIO header for portable power. Ensure correct polarity when connecting the battery.
2.3 Initial Connection
For development, connect the board to your computer using a USB Type-C cable. This connection facilitates power, data transfer, and firmware flashing.
3. Operating Instructions
This section details the various functionalities and how to utilize them.
3.1 Wireless Communication (Wi-Fi and BLE 5)
The ESP32-S3 chip supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE). The onboard antenna provides reliable wireless connectivity. Developers can use the ESP-IDF framework or other compatible SDKs to implement Wi-Fi and Bluetooth functionalities for network communication, data transfer, and device control.

3.3 6-Axis IMU (QMI8658)
The onboard QMI8658 6-axis IMU combines a 3-axis accelerometer and a 3-axis gyroscope. This sensor enables the detection of motion gestures, step counting, orientation tracking, and other motion-related applications. Developers can interface with the IMU via I2C or SPI protocols, depending on the specific pin configuration and library support.
3.4 TF Card Slot
The integrated TF card slot allows for external storage of pictures, files, or application data. This is useful for applications requiring larger storage capacity than the onboard Flash memory provides, such as logging data or storing display assets.
3.5 RGB LED
The built-in RGB LED, located behind a clear acrylic sandwich panel, can be controlled via software to produce various lighting effects. This feature can be used for status indicators, visual feedback, or aesthetic enhancements in your projects.
