-Here we have the Motor Driver and the Battery Charger/ adaptor. Take another Chassis plate and keep the orientation the same as the previous one. Also have the Zio Motor Driver,  and the Data Convertor from LiDAR's box handy. You can disconnect the wire from LiDAR as we will attach it later.

-Use the included USB A to USB C cable to connect the Power Distribution Board to the beagle. You can pass the wire through the inside of the spacers in order to keep everything clean and no wires hanging around. Also, connect all 7 jumper wires to Raspberry Pi based upon the connections given on the connection sheet. You can also refer [Raspberry Pi GPIO diagram](https://www.raspberrypi-spy.co.uk/wp-content/uploads/2012/06/Raspberry-Pi-GPIO-Header-with-Photo.png) for checking out the pin numbers.
