Product parameters:
Size: 33.4 * 25.6MM
Voltage: 3.3V, 5V
Port: the digital quantity level
The output load voltage: 0 to 24V
The output load current: < 5A (more than 1A need to add heat sink)
Platform:  MCU, ARM,

The product features:
Using original IRF520 power MOS tube, can adjust PWM output
Can let the drive up to 24 v load, such as LED lights belt, dc motor, micro pump, solenoid valve
By PWM adjustable can realize stepless dimming LED, motor stepless speed regulation

The product instructions:
PWM signal for high level effectively
When the PWM for high level (3.3 V to 3.3 V) :
As the power supply voltage, between V + and V - working indicator, work load
When the PWM is low level (0 V to 0.5 V) :
V + and V - between 0, work lights out, don‘t work load
