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

Description:1 .Input: DC 6V - 12V (input voltage m u s t be higher than the output voltage to 1V or more.)2. Output: 3.3V (+ - 0.05v error), 5.0V (+ - 0.05v error), 800mA (load current can not exceed 800ma), 12V (12V input directly to output)3. Pairs of panel design, layout, nice;4.Specially designed two pin mounting holes, can be directly fixed to the tunnel plate to extend the experiment;5 Using a plurality of input and output pin, easy to use and connect;6 PCB board size: 4.5cm * 4.5cm7 With power indicator light (red)
