Review on 🔌 HiLetgo 5pcs Power Supply Module for MB102 Prototype Breadboard - 3.3V/5V, DC 6.5-12V or USB Power Supply by Richard Muncy

HiLetgo's five 3.3V/5V power supply modules seem pretty good for the price. One was disassembled and the other four had to be disassembled. Each of them completely broke their pair. The connector pins on the loose block had to be straightened to fit the breadboard. The other four were fine. The visual inspection of the modules showed that the processing is quite good. Surface mount parts are well matched to pads. The soldering flux remained on the contact pins. never mind In terms of accuracy, here are the readings from my old but trusty Fluke 77 multimeter: 4.98/3.27, 5.00/3.29, 4.95/3.29, 5.04/3.30, 4, 92/3.32. These numbers were obtained with 12 volt DC input and no load on the outputs. Once I've built the project, I'll re-evaluate these blocks as they are used and update them if there are any noticeable changes. At the same time, I think five stars is a fair rating.
