The module is a high-current MOSFET driver module with low on-resistance.
It can drive a DC fan, motor, single color LED Strip, high power LED,
then the speed and the brightness can be adjusted via PWM whose frequency should be less than 20KHz.
It is compatible with Arduino/AVR/ARM/PIC.
1 Output current up to 3A (Resistive load)
2 External power supply can be 4.5 ~ 13.5VDC
3 Interface logic level can be 3.3V / 5V
