PCB Terminals

Looking at the picture we have a total of 7 blue screwdriver connectors. These connectors are called PCB Terminals. That is the official name. You can search on the internet for it and you will see many other such terminals.

The two on the left are for motor A. In our case these will be used for the back motor that will drive the car forward and backwards. On the right, we have two other blue connectors that will be used for turning left and turning right. 

Input Pins

There are four pins on this driver numbered 1 to 4. These are called input pins and they should be connected to the controller. 

Jumpers

We know. We know. It is getting quite tedious with the new names. Only three more. We promise. 

In the picture below, you could see 2 of the 3 jumpers that the motor driver has. They are highlighted. The jumpers simple connect the output PCB Terminals to the Input Pins. 

Capacitors

We are not going it use them in any way during this course. The capacitors are the two large cylindrical elements.

Radiator

Where there is current there is also heat. The goal of the radiator is to disperse this heat. 

The driver from Below

Take a look at the driver from below. In the picture, you could see the out 1,2,3,4 highlighted.
