DROK USB Buck Converter, 4pcs DC-DC Step Down Module, 6-32V to 5V, QC 3.0 Charging, Power Supply Voltage Regulator, Black

I removed the USB connector as I wanted to direct-wire a USB cable to the board. I would be nice to have a solder-pad output option rather than only the USB port.

Product looks as sold. Each unit has performed well. Recommend!

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.

Fonctionne tel qu'espéré.

Not worth money. S Wouldn't recommend as everyone of them drained battery. Went to local electronic store and the difference is amazing. 10x beefer for 2x less the cost of this seller. Don't buy! Small components.
