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:
| Pine | Name | Function | Notes |
| 1 | 1.2 IN | Activation engine 1 | 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. |
| 2 | 1 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. |
| 3 | 1Y | Motor 1 Power | This pin must be connected to one of the pins on the motor continuous. |
| 4 | Mass | Mass | This pin must be connected to ground. |
| 5 | Mass | Mass | This pin must be connected to ground. |
| 6 | 2Y | Motor 1 Power | This pin must be connected to one of the pins on the motor continuous. |
| 7 | 2A | Engine 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. |
| 8 | VCC2 | Power Source engine | This pin allows you to power your motor (max 36V) |
| 9 | 3.4 IN | Engine 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. |
| 10 | 3A | Motor Forward 2 | A (HIGH) 5V on this pin will allow the engine to run in one direction. The speed can be controlled using a PWM. |
| 11 | 3Y | Motor 2 Power | This pin must be connected to one of the pins on the motor continuous. |
| 12 | Mass | Mass | This pin must be connected to ground. |
| 13 | Mass | Mass | This pin must be connected to ground. |
| 14 | 4Y | Motor 2 Power | This pin must be connected to one of the pins on the motor continuous. |
| 15 | 4A | Engine 2 Reverse | A (HIGH) 5V on this pin will allow the engine to run in reverse direction. The speed can be controlled using a PWM. |
| 16 | VCC1 | Logic Power | Circuit power (+ 5V) |
