This is a regulator board. It has a terminal strip with a common ground, input, and adjustable VDC output. Includes fuse, filter, and power LED. It uses the adjustable version of Dimension Engeering's step down voltage regulators.

The switch mode voltage regulator is designed to be the easiest possible way to add an adjustable voltage source to a new or existing project with all the efficiency benefits of switch-mode power. The switching regulator is pin-compatible with the common 78XX family of linear voltage regulators used in TE-045-005. It has a small screw on top that allows you change the output voltage as your project evolves.

The Switching Regulator can deliver a maximum of 10 Watts.

The screw potentiometer on DE-SWADJ is worm-gear driven, so small vibrations and movement will not cause the voltage to shift. Use of glue to hold the screw in place is strongly discouraged and could damage the device.

We use these in our ATRs to supply a regulated isolated efficient regulated supply from a battery to our robot accessories. The board is spaced out on 0.1" or more grid that is easy to solder with no surface mount components. The board is about 1.25" square.
