 ## Calibration:
-[Calibration](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC/wiki/Calibration) is not required with USART control, but can be done if you use an input devices(e.g. Joystick or Throttle handle) on the Arduino and are not taking care of calibration center value and min/max range there.
