 ## Pin Mapping
 This is the pin mapping this firmware is using, you might have to adapt it to your board variant in [defines.h](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC/blob/master/Inc/defines.h) file

+Some boards have 6 wires on the hall sensors cable, with an additional white wire. For those you can use the alternate mapping by changing parameter BOARD_VARIANT in [config.h](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC/blob/master/Inc/config.h)
