Description: Using original power MOS tube, can adjust PWM output Can let the drive up to 24 v load, such as LED lights belt, for dc motor, micro pump, solenoid for valve By PWM adjustable can realize stepless dimming LED, motor stepless speed regulation 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'for t work load Material: Electrical Components Product Color: See Pictures Output load voltage :0-24V Drive up to 24V allows the load, such as LED lights, for DC motors, miniature pumps, solenoid valves Output load current: <5A (1A above need to add heat sink) Platform: MCU, ARM, Raspberry pie Length: 3.3cm/1.30'' (Approx.) Width: 2.5cm/0.98'' (Approx.) PWM dimming LED can be used to achieve stepless dimming, variable speed motor No Retail Package Quantity:5 Pcs Note: Due to the difference between different monitors, the picture may not reflect the actual color of the item. Package includes: 5Pcs x IRF520 Driver Module
