DC-DC 12V To 3.3V 5V Buck Step down Power Supply Module For Arduino

Description:
1 .Input: DC 6V - 12V (input voltage must be higher than the output voltage to 1V or more.)
2. Output: 3.3V , 5.0V (+ - 0.05v error), 800mA (load current can not exceed 800ma), 12V (12V input directly to output)
3.Specially designed two pin mounting holes, can be directly fixed to the tunnel plate to extend the experiment;
4 Using a plurality of input and output pin, easy to use and connect;
5 PCB board size: 4.5cm * 4.5cm
6 With power indicator light (red)
