Input control voltage :3.3V-12V
        Output charged voltage: 5-36V
        Board use of opto isolated, completely separated from the 2-terminal voltage.
        Input is controlled by a 2 pin control ,a ground control can be directly connected to the control switch.
        Control current 1-5MA control voltage is different, the current difference is mainly the loss on the LED.
        Charged with maximum current: 22A ,more than 5A need to add a heat sink.
        Board with LED lights
        Host input and output screw terminal block
        Control terminal using 2.54MM pin, easy wiring.
        Control can be directly connected microcontroller IO. MCU can ARDUINO PWM control motor speed,

the brightness of lights and so on. Note that large current need to add  additional heat sink
        Board size: 4.2 X 2.6 cm
