There are many places where we need to perform rotary work but with very high precision, like in manufacturing units, the robotic arms need to work very precisely in order to achieve the goal. That is when a stepper motor comes into play, which got its name from the fact that it rotates in steps.
We also use a motor board while using the stepper motor. The board has a connector that mates the motor wires perfectly which makes it very easy to connect the motor to the board. There are also connections for four control inputs as well as power supply connections.
The motor board for 2 channels consists of 6 pins, namely:-
1. A1
2. A2
3. VCC
4. GND
5. B1
6. B2
The stepper motor has a motor with connector pins to make the connections.

Safety Measures to follow
1. Do not use the driver or the motor under conditions that exceed the specification values.
2. Make all connections as small as possible
