The YYNMOS-1 module includes an IRFS305-S power N channel MOSFET transistor and a L217 general purpose optocoupler, integrated in the same board. You can use this module to isolate and control high current loads directly from your microcontroller.

Specifications:

• Signal voltage: 3-20 V,
• Output port voltage: 5-36 V,
• Maximum output current: 10 A, 
• PWM frequency range: 0-20 kHz,
• Dimensions (in mm): 37.5 X 23 X 16. 

Typical applications:

The output port can control high power devices like: motors, lamps, LEDs, DC motors, pumps, valves, etc. 

Pinout:

• DC+: External power supply positive, 
• DC-: External power supply negative,
• PWM: Input signal positive,
• GND: Input signal negative,
• OUT+: output port positive (connect it to load positive),
• OUT-: output port negative (connect it to load negative).
