More info

The integrated circuit is a SN754410 Quad half H-bridge to control easily a motor Stepper with two coils.

It allows to control a current of 1 has under a voltage of 4.5V to 36V to power the engine coils step-by-step motors continuous relays, coils.

The inputs are compatible in TTL and CMOS low level level.

Example usage to control 2 Motors continuous:

PineNameFunctionNotes
11.2 IN Activation engine 1By putting this pin to 0V (LOW or GND), this will cut the power to the motor and putting it to the 5V (HIGH), this will activate the motor power supply. 
21 A Engine 1 Forward 

A (HIGH) 5V on this pin will allow the engine to run in one direction.

The speed can be controlled using a PWM.

31Y Motor 1 Power This pin must be connected to one of the pins on the motor continuous. 
4 MassMass This pin must be connected to ground.
5 MassMass This pin must be connected to ground. 
2Y Motor 1 Power This pin must be connected to one of the pins on the motor continuous.  
 2AEngine 1 Reverse 

A (HIGH) 5V on this pin will allow the engine to run in reverse direction.The speed can be controlled using a PWM.

 VCC2Power Source engine This pin allows you to power your motor (max 36V) 
 3.4 INEngine 2 Enable By putting this pin to 0V (LOW or GND), this will cut the power to the motor and putting it to the 5V (HIGH), this will activate the motor power supply.
