Optical Isolation Motor Drive Module w/2 DC 3V-6V Speed Decreaser Motors
Overview:
1. L293 Small motor drive chipset; working voltage is 4.5-3.6V; Maximum drive current is 1 A.
2. Two DC motor interfaces; One 4-stepper motor interface.
3. Strong and weak electric power worked by Optocoupler isolation, maximizing the distraction influence for MCU from electromagnetic.
4. Two H-bridge drivers are convenient to make pulse-width modulation (PWM).
5. Use a locking type terminals, easy to connect a DC motor and motor power.
6. Separate power supplied for motor drive and logic control, which can use 3.3V or 5V system control.
7. There is no over-current protection in the inner chip. Please keep in mind the motor current must not too large.
