10 Pack XL4005E1 DC to DC Buck Converter 5-32V to 1.25-30V Power Supply Step Down Module

These little guys solve a lot of small problems. Maybe you just have a light, or a fan, of a digital display that needs a reduced and stable voltage. Maybe you need a 5 Vdc display, to put in a 12 Vdc vehicle. These make it easy, as long as they will supply enough power for your application.

The best of the best... great regulation and a impressive current handling.

These work extremely well.
