Review: Buck down to 5v - Working great
Review: Great for integrated solutions - Great little modules we use within our line of products to run a microcontroller off of 12v. Very low RF noise compared to other buck converters we have tested and stable voltage. We can't really speak as to how they work under high load, as we only draw about 20mA from them, but we load test each one at 2 amps for 30 seconds and I don't believe we've ever had a dud out of 100+. At the power levels we draw heat is not an issue at all but it would be important to test this for high draw applications. We typically see a power conversion efficiency of about 85% from 12v to 5v@2A when load testing. Module size is always extremely consistent, which is important as we insert them into an enclosure with extremely tight tolerances. We chose this module for our product because of the consistent specifications, low cost, and low noise which is important as our microcontroller generates audio for a radio.

## Questions & Answers

**Q: could this be used to power a raspberry pi? wondering if it will be able to output the 5.1v at 3 amps constantly**
A: I use them to power Pi 3b+ and Pi4.  No problems at all.  The Pi's are used in radio applications which use 18.8V power.  More convenient to power off the 13.8v power rails.  I also use it to power a Pi3B+ used in Octoprint for my Ender 3 printer.  24v power taken from the Ender 3 power supply through the buck to power the Pi.

**Q: Do you have a suggested way to mount these usb boards? Is there an adapter housing?**
A: I used Hammond 1551USB2BK housing and mounted using epoxy.

**Q: Does this have low voltage protection that automatically shuts off when voltage drops below 12 volts? If so, can you turn it off?**
A: The input range is 6-32V. I operate mine at 6-8V typically. You don’t have to do anything special for this.

**Q: do they auto cut off when battery is charged?**
A: No.  As long as there is power to the converter it will supply power at the USB port.  The device being charged should have its own battery management system to cut off power when appropriate.

### ⭐⭐⭐⭐⭐ A solid compact circuit of high quality
*by E***W on April 8, 2024*

At the risk of sounding like an A.I review , I have used Drok products in many situations and they always excel. In this case, I hooked this device up to my very accurate meter while connected to a deep cycle battery and the output was 5.244 volts. It is flawlessly powering a traffic camera in my car while wired to a 12 volt circuit in the windshield mirror so that no wires hang down towards the cigarette lighter. When switched on there is a tiny red led to indicate that it is energized. It is held in place by two sided tape as the back of it is smooth. It has a crude USB A ( the original larger USB ) outlet and two options for power input, a wire terminal and jack.
