[2022 New Version] Breadboard Power Supply Board Module 3.3V/5V Dual Voltage with Fuse Protection

Have short circuit protection. Good value. Works as expected.

One of the two power supplies did work well. After some troubleshooting I determined that latch switch was the incorrect version. Thankfully I had a pretty good Scooby clue, the switches on the two supplies were different colors. In the end I chose to keep them, I removed the incorrect switch and solder in jumpers to get it to work.

Good value for the money. The output voltages are accurate to the second decimal.

Great product - plugs into both power rails of a breadboard to provide 3.3v or 5v to either rail (independently selectable, as well as off). There are also 2 3.3v and 2 5v headers on the board to pull power from. The power switch is a nice touch if you want to leave your power source plugged in. It also takes DC, Type-A USB and micro-USB for power input, which is convenient.The seller (MakerSpot) customer service is also top-notch. I received one unit with a faulty switch (in testing, one of the poles of the DPDT was not working) and they immediately responded to resolve the problem.

I'm surprised I didn't fry my microcontroller. Amazon, of course, replaced it and the replacement output the correct voltages. One thing I like about it is the power input jack is on the outside of the device when its plugged into a breadboard - unlike others I looked at.

This PS is exactly what I wanted in a breadboard power supply. No more batteries.

Easy to use and very handy. I love the on/off latch switch. Removed the DC in plug and large USB connector since I just use the small USB connector.

I like this one because it has the micro USB which others don’t.

Fonctionne bien sur adapteur mural 9V 1A (centre positif). Les valeurs 3V et 5V sont bonnes sur les 2 rails. Par contre, et c'est vraiment étrange, le module a été monté avec un interrupteur inversé (normal closed switch). Donc pour l'alimenter, on doit mettre l'interrupteur à OFF, et pour le fermer, on met à ON. À lire les autre commentaires, on peu facilement déduire qu'il y a des enjeux de contrôle de la qualité avec ce produit. Donc, avant de brancher quoi que ce soit sur ce module, je suggère FORTEMENT de tester les bornes avec un multimètre sur réception du module.

I wonder if it goes to the specified current. I just plugged a simple ESP8266 and that thing choked.

Basic piece of hardware, but it's nice to see a micro-usb connector on top finally

ne peu plus m`en passer .

Reçus rapidement tel que d'écrit. .Fonctionne parfaitement lorsque l'on applique les jumpers aux bonnes bornes...
