How to use a Breadboard Power Supply

This video I am going through Breadboard power supply modules where to get them, how to setup it up and testing certain parts.
These Breadboard power supply's are very helpful when testing your projects on a breadboard as it removes the power requirement from your microcontroller such as your Arduino, RaspberryPi, ESP32, ESP8266 ect.
Being able to switch the voltage levels in the rails very easily is also a bonus just make sure your connected circuit supports the voltage you have selected on your rails.

Super helpful video. Exactly what I was looking for!

[@SteveH-TN]

Thanks for sharing your experience and this video.

[@ParadoxTransistor]

Very clear explanation, nice video!

[@zabity]

thanks for the vid Scotty! As a green man who wants to practice the basics, I'm wondering whether it's a good idea to connect the board to my house network - a power supply connected to an outlet in a wall. does it pose any risk to the whole network?

[@cameronstarling379]

How come when I connect green and yellow LEDs to the 3.3v rail it fries them, but red LEDs are fine?

[@drpreag]

I power it with 12v, but on 5v rail I have 9-10v output, not 5v. 3.3v rail is ok. Is this normal?

[@sevfx]

I have the MB102 power supply hooked up with a 9v battery. My problem is, it seems to be really unstable, with fluctuating voltages depending on the load. When i choose the 5V mode with nothing attached, i only get 2.9V on the rail. When i place in an led, the voltage on the rails instantly drop down to 1.9V. Are that normal loading effects, or is the battery to weak? i cant figure out, what is going on. Are that common problems?

[@Shaorune777]

same happened to me.
I have switching power supply of 5v 10a.
this board seems kinda like stepdown Volt. dunno why.

[@sourishghosh4628]

get a wall adapter like 9V or 12V and plug it in through DC jack also this module can out put current upto 800mA iirc, and yeah the chinese variants can be faulty sometimes the usb connecter is unregulated etc etc

[@Brandon-qp7gq]

For the power supply you showed, is ground the same as the positive or negative rails?

[@ByteMeCompletely]

yes.

[@ivarnordlkken8082]

Ground is the negative.

[@jocool7370]

I have on of those where the USB is a power output, not an input.

[@msfmapper]

Can I power it through 5V 2A power adapter?

[@reasonoflife1620]

Depends on how much volts the supply can hold

[@hstone0808]

What if I ran 8.4 volts but like 3000 mah, will that burn it out?

[@ivarnordlkken8082]

It can tolerate 12 V.

[@daz41262010]

new sub I will checkout a few more of your videos :)

[@Gouth83]

12v power supply not working why?

[@everestdesign7]

How do I get 9v output?

[@3ankif109]

you can't. its either 5v or 3.3v. Otherwise you can just use a boost converter to get 9v

No, sorry. This is English.
