DROK Buck Converter 12v to 5v with USB Type C, 24V to 12V Step Down Converter Adjustable DC Voltage Regulator 8.2V-32V to 3V-20V 4.8A Volt Transformer Power Supply for Type C Charger Fast Charging

I used this to run a Raspberry Pi 4B and a 5V DC fan off of a 12.8V LiFePO4 battery. The Raspberry Pi was connected to the USB output while the fan was connected to the screw terminals. I had no issues with voltage or current whatsoever.

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.
