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 ช่องเสียบการ์ด TF
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.
ไฟ LED RGB 3.5
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.
