2 custom firmwares are available for flashing the sideboards that are coming with the hoverboard mainboards.
Those sideboards handle:
- Leds 1/2/3 to show battery status for any variant except the transpotter variant
- Led 5 for reverse and braking with Hovercar variant
- Optical sensors that can let you turn on/off some of the features (e.g. Hovercar variant )
- RC receiver with iBUS protocol can be connected to the AUX serial Rx pin (Hovercar variant)
- An Inertial Measurement Unit that is meant to be used with the Hoverboard variant (
⚠️ The balancing is not implemented yet⚠️ )
Those are not meant to control motors.
The GD firmware can be used on boards with following chips:
- GD32F130C6T6
- GD32F130C8T6
The STM firmware can be used on boards with following chips:
- STM32F103C8T6
- GD32F103C8T6
Those boards can have different IMUs, not all are fully supported:
IMU | Datasheet | Raw Accel. Data |
Raw Gyro Data |
DMP Available |
DMP Supported |

The Digital Motion Processor handles the calculation of Euler Angles and Quaternions.
If you find a board with a different IMU, please use the debug variant and try:
- a command : you should see raw Accelerometer data, if you see non zero data, it proves the firmware supports the Accelerometer
- g command : you should see raw Gyroscope data, if you see non zero data, it proves the firmare supports the Gyroscope
- e command : you should see Euler angles, if you see non zero data, it proves the firmware supports the DMP
Please share your findings so that we can enrich the wiki.
