UCTRONICS DC 9V 12V 24V to DC 5V 5A Buck Converter Module, 9-36V Step Down to USB 5V Transformer Dual Output Voltage Regulator Board [2 Pack]

Great item, it handles varying powers quite well, and is easy to use for many things, as it has screw terminals on both sides and a 12v barrel jack input, and a USB connection that sent the 5v over the power lines. Relatively cheap, but it does not have screw holes, so implementing it may be a bit difficult.

converts down to 5 v from 12 to run raspberry pi 3+ perfect

Originally bought these due to the noted 5.2V 5A output capacity which is the ideal rating for a power hungry Raspberry Pi 5. It also helped resolve some power related issues with some equally power hungry 5G M.2 modems that I had been utilizing. I'm very happy with these. Great price and does exactly what it needs to and meets all the ratings it is advertised for. An additional pro-tip: Look up USB-C PD trigger boards or cables. Many all over Amazon. I have my setup fed by a 15V PD trigger board on the input side which allows me to use a more widely available PD power supply/battery bank and supply the necessary wattage. SUPER convenient. I've powered my rig on everything from a Steam Deck charger, power bank, USB-C PD car charger, etc..

Nice little buck regulator. Hooked it up to a load tester and it cranks out 5-6 amps as advertised. Low ripple, no voltage dips at all. At 4 amps, though, the SMD diode on the input side gets to 98C and will probably not last long at higher. The cap next to it gets very hot too. Should be OK with a fan blowing over it.

Excellent! I used it to power a guitar pedal from a 9V pedal power supply. I only needed to add a 9V reverse-polarity connector, since most power supplies output tip-negative and the Utronics is tip-positive. I just wish there were a case or cover for it.

Works perfectly to power raspberry pi 4b in car.

They worked really well.

I have only bought 2 of these and I really like them for my projects. I plan on buying more in the future. Great product.

ラズパイ5の電源用として購入しました。 出力5Aが出るか不安でしたが、起動後もエラー無いので良さそうです。 基盤がむき出しなので気を付けて配線と取り付けしてます。
