TL. DR.

Connect Raspberry Pi 5V output to driver 5V. Connect the controller ground to motor driver ground 

Motor Drive VCC and GND

The Motor Driver has 7 PCB Terminal Connectors - those blue things. 4 of them are for the motors. One is for 5V voltage (coming from the controller), one is for 12V voltage (coming from the batteries) and 1 is for GND. We would use those for the motors in the next section. In this tutorial, we must connect the motor driver VCC and GND. The basic reason is that without this connection we won't have a proper connecting between the motor driver and the controller and the whole system won't work.

 How to connect them?

Take a look at the picture below. We have the three PCB Terminal Connectors in blue. From left two right these are 12V, GND, 5V. 

12V is connected to the batteries. Red cable to the left.

GND is connected to the batteries and to the controller.

5V should be connected to the controller. Red cable to the right.
