Controller Pinout

1 -Power plug.
2 - Three terminals - motor windings A, B, C. Current sensors on each pole.
3 - 5 pins - hall sensors on the motor.
- 5v, A, B, C , GND. No Temperature sensor.

The controller checks sensors at power up. To run without a wheel, it is necessary to close the at least one signal pin to the ground, but not all 3.

4 - 4 pins - the interface to the controller in the steering wheel. signals are : GND - common P - power from the battery, a high impedance output. Data - Serial interface
- 5V - rises after the charge and feeds into the steering wheel. The signal P turns on the scooter.
5 - 3 Pin - interface to the BMS signals are : RX/TX - serial interface. L - line on the LED stop signal.
6 - G, D, C, SWD are unsoldered. Microcontroller is STM32F103C8T6. Closed Fuse for reading.
