+This variant can be used to control the board from another board(e.g. Arduino, ESP32, ESP8266,RASPBERRY PI) or a computer via a serial protocol.<br />
+The example [Arduino sketch](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC/tree/master/Arduino/hoverserial) will send commands and process the feedback.
+
+## Wiring:
+* Connect blue wire to RX, blue wire to TX and black wire to GND of Arduino on right sensor cable(shorter)
+
+⚠ Red wire from sensor cable delivers 15v !!!
+Use 3.3v from programming port, 5v from hall sensor cable, or a voltage regulator.
+
+## Calibration:
+Proceed with [calibration](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC/wiki/Calibration) for better control if you use input devices(e.g. Joystick or Throttle handle) on the Arduino.  
+
+## Troubleshooting:
+
+If the board is beeping
+* Make sure the baud rate is 38400
+* Make sure you are using the sensor cable(left=USART2 or right=USART3) selected in config.h
+* On some boards the wire colors might differ, try switching blue and green wires
