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. Module features are as follows: 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; 4 High-level input current is less than 1mA 5 Standard electronic bricks interfaces easy to use 6 4 M2 screw mounting holes
