In the grand pursuit of knowledge within the domain of physical computing, one finds few allies as stalwart and as capable as the HiLetgo 5pcs 3.3V 5V Power Supply Module for MB102 102 Prototype Breadboard. This tool, much like the bulwark of a steadfast fortress, stands resolute against the vicissitudes that often plague the landscape of educational electronics.Armed with dual voltage capabilities, this module gallantly offers both 3.3V and 5V outputs, catering adeptly to the diverse requirements of our youthful scholars' projects. Its seamless integration with the MB102 breadboard serves as a testament to its strategic utility, ensuring that our academic endeavors are not hindered by compatibility or connectivity skirmishes.The power options, spanning DC 6.5-12V or USB, furnish our educational theatre with an unparalleled versatility, allowing us to conduct our experiments in a variety of settings, unfettered by the chains of limited power sources. The robustness of its build and the constancy of its performance are akin to the reliable engines of war that powered victories of old.In terms of fiscal prudence, the module's affordability makes it a veritable boon for the budget-conscious, enabling students to extend their forays into the realm of electronics without the specter of exorbitant cost hovering over them.Thus, to any fellow educator marshaling their forces in the often unpredictable field of applied computer science and electronics, I commend to you the HiLetgo Power Supply Module. It is not merely a tool, but a critical ally, sure to fortify your educational arsenal and bolster the spirits and skills of those in your charge.

I tested all 5 power supplies and all were within 1% of the nominal voltages. They all fit my breadboards perfectly. Quite handy while prototyping, whether it's a 5v or a 3.3v project.

The way they packaged them was kinda half a**ed. One of them actually came broken and i could use it.

All five operate properly and tested with a couple 12VDC adapters plus a 9VDC; all came fully assembled plus appears to be a quality product (e.g. board, parts, solder joints). Also, measured with a digital multimeter and determined 3.3v exact from all but 5v for three (with two reading 4.96v) on the higher voltage pins. Therefore, all five are perfect for my purposes. As pictured, I powered microcontrollers via breadboard, header pins, and USB (output-only) successfully. I would repurchase again from this supplier. (Note: the recommended input range is 7 to 12 volts DC; I also tested with a 5VDC adapter and measured 3.3v but only 4.6v for the greater voltage output pins, which isn't surprising since some regulator loss is expected)

These seem very sturdy and because they are HiLetgo, I trust that the electronics are safe and good quality.They attach well to the breadboard and don't take up much space.They are versatile, as you can have either 5V, 3.3V or both fed to the breadboard. They also have additional power pins that you can use without the breadboard.It's very handy to have the power switch, so you can just power things off right at the breadboard.The packaging is lacking some as some of the pins were bent when it arrived. I straightened them out and things are still working. It is a little worrisome that this may have created a weakness that will cause problems later on.The only disappointment I've had is that it consumes part of the power. I should have realized this. It turns out that I need 7.5V coming in to get a full 5V of output. After switching to a better power supply, I'm fully satisfied.I'd recommend this highly.

The solder joints are so bad,"How bad are they?"The solder joints are so bad that just pushing the pins into a breadboard causes them to release from the PCB.Horrible quality. Every unit is the same.

The Power Supply Modules from HiLetgo perform solidly. Delivering a Constant 5.0 DV Volts from your supply source. Whether a 5V Power Supply or a 9 Volt Supply. I found the delivered 5VDC to be very uniform and constant with a Varying Load. The Power Supply firmly attaches to any breadboard, from new to will used. A very nice small footprint and the capacitors for filtering and providing linear control work as intended. I will probably by another 5 units as the Price Point is Very Attractive. I have bought other items from HiLetgo and have always found a nice quality product that performs to the intended requirements of one's projects.Sincerely Robert Tonkavich
