🔌 High-Quality JacobsParts Mini360 3A DC Voltage Step Down Power Converter Buck Module – Multiple Output Options (3.3V, 5V, 9V, 12V) – Pack of 10 Review

Out of the 5 I've tested so far, 2 turned out to be DOA. It wasn't really a problem as I really only needed one and for the price I'm not upset that one of them was DOA. Otherwise, the ones that work will work. I'm drawing a little less than 1A and haven't tested them to the claimed 3A so can't comment on that. Note: I used reasonable ESD protection when working with them, so they definitely didn't work. when they arrived.

good quality board and components. The inductor got a little warm at 1/2 amp (0.5 amp) so I'm not sure it will run at 1.8A continuously, but for the price it's a great deal. Would (probably) buy again. UPDATE: Had to deduct a star, I'm still with my original opinion, I would buy it again BUT beware the output ripple voltage is pretty bad. I've had some really weird issues with a few different microcontrollers I've used (despite putting decoupling caps in). Then I took aim and found a terrible…

Pros: Really tiny, kind of fits on a breadboard. Works at smaller currents. Cons: I've been trying to control a digital LED strip and while the module seems to work fine, it gets very hot. I can smell heat after about 1 minute of continuous operation (at 5V, 1.45A). The other, driving the ESP32 and audio player/amplifier module, works well without getting hot. The ESP/Audio setup draws between 10mA and 30mA (I haven't tested the audio output though. Most likely the results will be the same)…

Bought a set of 10 adjustable buck LED lighting controls. You get what you pay for in this case. It's so terrible! A quick test on my desktop showed how bad. I set it to 5V (no load), input 12V. With only 0.5A load, >1.0V ripple at 340kHz! BAD! The adjustment dropped to an average of 4.4V. So I increased it to 5V. (then it was 7V without load) So everything will only get worse. At 2A it began to truncate periodically. The thermal imager showed the chip as the hottest part, about 70 degrees…

My rule of thumb *is* the smaller the buck converter, the smaller the phantom load. So I always try to use the smallest buck converter that can get the job done. I needed to power a weather station that only draws a few dozen amps. I figured it would be ideal to use this little buck converter to provide the required 5V from a 12V battery. When I accidentally put my finger on the device, I felt it was warm. At first I thought it was just heat from the wires soldered to it. but no. this thing is…
