Description

Product characteristics

Using the original IRF520 power.MOS tube, PWM
the control output can be performed.

The Arduino can drive loads up to 24V, such as LED
strips, DC motors, micro-pumps, and solenoid valves.

With PWM modulation, LED step-less dimming and
motor step-less speed regulation can be realized.


Product instructions:

The PWM signal is active at a high level

When the PWM is high (3.3V-5.0V) :
Between V+ and V- is the power supply voltage,
the work indicator is on, and the load is working

When the PWM is low (OV-0.5V) :
If the value between V+ and V- is 0, the work
indicator is off and the load is not working

The VCC pin setup is useless, V+ and VIN are
