Step-down DC-DC Power Converter 25W

missing supply of cable for white connector and documentation

With multiple outputs, almost no power loss, form-factor and easiness to use this is really the best adjustable dc-dc I could find on the market.

This board has 3 different types of output connectors, variable voltage, an on-off switch, and can pass through the input voltage if you want to chain it to another regulator. Large footprint however.

The convenience and capability of this module is unmatched. It remains incredibly cool at all times, unlike other modules I've tried. It offers some very convenient methods of hooking up to it too, with a bunch of outputs.

A very well breakout, small and robust.
