GENERAL NOTES: GENERAL NOTES:
- All the calibratable motor parameters can be found in the 'BLDC_controller_data.c'. I provided you with an already calibrated controller, but if you feel like fine tuning it feel free to do so. - All the calibratable motor parameters can be found in the 'BLDC_controller_data.c'.

The original Hardware supports two 4-pin cables that originally were connected to the two sensor boards. They break out GND, 12/15V and USART2&3 of the Hoverboard mainboard.

Both USART2 & 3 can be used for UART and I2C, PA2&3 can be used as 12bit ADCs. Both USART2 & 3 can be used for UART and I2C, PA2&3 can be used as 12bit ADCs.
