+### :control_knobs: Calibration:
 Proceed with [calibration](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC/wiki/Input-Calibration) for better control.<br>
 With this variant, the auto-calibration is expecting 2 normal pots, and will reject the calibration if an input is missing or is of incorrect type (e.g. mid-resting pot). <br>
 You can change the type of input1(brake) to 0 to disable it if you have a mechanical brake and don't need this input. But you won't be able to use it to reverse anymore.

 - The wheels oscillate when braking: this is normal behavior when there is no load, it won't happen with the wheels on the ground.<br>
