LTC1871

 The module has high power output and efficiency (up to 96%). The output can be up to 65W (and can further reach 100W when enhance heat-transfer).

Onboard we have a voltmeter to show clearly the input / output voltage (we can select to show input/output voltage by pressing on the button onboard). When the “IN” LED lights on, the voltmeter displays input voltage; When the “OUT” LED lights on, the voltmeter displays output voltage. We can also turn off the voltmeter LED by removing the jumper cap at “P3 (please refer to below image)”. You can easily adjust voltage by the potentiometer onboard and the voltmeter onboard. You won’t even need a multi-meter when adjusting. Very convenient.
