⚠️ Not implemented yet ⚠️
The balancing part of the FOC firmware has not been implemented.
-There is a firmware for sideboards with [GD](https://github.com/EFeru/hoverboard-sideboard-hack-GD) and [STM](https://github.com/EFeru/hoverboard-sideboard-hack-STM) chips, but it's only supporting the DMP on MPU6050 IMU for Angle calculation.
+There is a firmware for sideboards with [GD](https://github.com/EFeru/hoverboard-sideboard-hack-GD) and [STM](https://github.com/EFeru/hoverboard-sideboard-hack-STM) chips, but it's only supporting the DMP on MPU6050 and MPU6052C IMUs for Euler Angle calculation.
Many sideboards have a different IMU like MPU6050A, which is in fact a ICM-20689.
The [Bipropellant](https://github.com/bipropellant) firmware handles the different protocols of the stock sideboard firmwares but it's not supporting FOC motor control.
