L293 Optical Isolation Motor Driver Module

Function features
1.L293 small motor driver chip, the working voltage of 4.5-36V, the maximum drive current of 1A.

2.Two DC Servomotor interface and a four-phase stepper motor interface.

3.Strong and weak electricity by opto-isolated and maximum avoid the MCU interference by electromagnetic.

4.Two H-bridge driver, can facilitate the achievement of the pulse width modulation (PWM).

5.Adopt locking-type terminal for easy connection to the DC motor and motor power.

6.The motor driver and logic control separate power supply, you can use a 3.3V or 5V system control.

7.The chip is not over-current protection, pay attention to when using motor current is not too large.

8.PCB size: 51.8 (mm) x39.3 (mm).
