The 3PCS 3X MB102 Breadboard Power Supply Modules are an excellent addition to any prototyping setup. Designed to convert DC 6.5-12V to 3.3V or 5V, these modules are compatible with Arduinos and may other microcontrollers and fit perfectly on standard breadboards.I've use these power supply modules often with projects, and they've consistently delivered reliable performance. The dual output options (3.3V and 5V) provide versatility, allowing me to power different components without needing mu...

Fits on my bread board and supplies power to both positive and negative rails. using the little jumper, the voltage can be adjusted from 3.3 to 5 so works with Pico and Arduino both.

The boards are half way processed. There are still score lines and extra board that they didn't finish breaking away. There's still Flux on the board so they weren't fully cleaned and but power button is inverted, depressed should be on and not off.-They work.-Voltages are a tiny bit high but within specification.-Had to scrub them with isopropyl to finish cleaning them up and break off the tab.-3 stars for having to do extra work to make them useable.

Just a Techie

This package was a set of three conventional breadboard power modules. They are designed to supply 3.3V or 5V to the power lines of a standard breadboard. Power to the module is supplied via a common 7-12 V barrel connector or a standard USB-A connector.Jumpers are used to determine whether a rail gets set to 3.3V or 5.0VIf supplying power via the USB-A connector, the 5.0V setting will actually be the voltage of the USB-A input. That means that if you can put a higher voltage on the USB-A con...

This power supply works. It basically takes any 6 to 12 volt DC input and puts them through two voltage regulators giving you 3.3 and 5 volts. The power supply has pins on the underside that fit many of the narrower bread boards. You can choose between voltages on both sides of the breadboard which is very nice.Sounds good. Unfortunately, there is no short circuit protection. The 5 volts regulator on two of mine failed when I momentarily short circuited the output. It then started putting 10 ...
