Features This driver uses original IRF520 power MOS tube, can adjust PWM output and can drive up to 24V load, such as LED lamp strip, DC motor, mini pump, solenoid valve. Voltage: 3.3V, 5V. Connection: Digital quantity level. Output load voltage: 0-24V. Output load current: 1A). Platform: SCM, for ARM, for Raspberry Pi. Weight: 4g (approx.). There are a total of five pieces of driver boards in one set that you can use for many projects. The maximum output current is 5A and a heat sink must be installed if a load of more than 1A is operated. PWM can be used to dim the LED infinitely and to control the motor speed infinitely. Specifications: Size: 3.5*3.2cm/1.3*1.2in Voltage: 3.3V, 5V Port: Digital quantity level Output Load Voltage: 0-24V Output Load Current: <5A (need heat sink if >1A) Platform: SCM, for ARM, for Raspberry Pi Weight: 4g(approx.) Package Includes: 5 x Driver Module Package List
