The DC-DC conversion module, adjustable step-down station, features high power, high efficiency, and low noise. It has a power indicator and a built-in voltmeter, which can be self-calibrating. The measurement can switch between input and output, with an indicator, and the voltmeter can also be turned off. The board uses terminal connections for easy wiring.
