🔌 UCEC MB102 Breadboard Power Supply Module for Arduino Board: Reliable Solderless Breadboard Kit (Pack of 6) Review

The first package was stolen and had to wait for a replacement over the next week. You received my package on Saturday morning. 4/6 pins were bent at the top, probably due to shipping, and the bottom pins were generally bent, but only slightly. I had mixed feelings about the lenses at first, but in the end I really appreciated that they arrived as quickly as they came, so I just sat down with a pair of tweezers and realigned the lenses. I just tested the latest board for functionality with some

I bought a set of six. In the beginning everything worked. The built-in voltage regulators of the AMS1117 must be current limiting and thermal limiting. But the ICs used on these breadboards are neither - I wonder why. In the meantime, four of them are defective due to a brief short circuit on the breadboard and pass on the input voltage to the output rail, some with a 5-volt regulator simply smoke until they fail, some burn with a continuous light after a failure. As nice as the shape is to…

It was a real failure. Of the five regulators, all five worked fine for 3.3V. But wait! There is less! None of them worked properly at 5 volts. 3D from 4.2 to 4.5. One is measured at line voltage (9V) and one at 6 volts. They're useless for microcontrollers unless you care if the problem is low voltage or your circuit. I can't understand how this got good reviews unless the previous reviewers only worked at 3.3V or never broke a multimeter. spend more.
