How to use a Breadboard Power Supply

The only extra point I'd make is that the two rails are not independent. They share a common negative (ground) rail, so you can't use them to produce a ± 5V split supply, as you could if they were two independent supplies.

Can I use a ac barrel jack? Would it hook up to the wall socket??

Thanks I bought one but it came with no instructions. Thanks for your clear explanation.

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

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

12v power supply not working why?

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?

Super helpful video. Exactly what I was looking for!

Very clear explanation, nice video!

Thanks for sharing your experience and this video.

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

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

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?

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

How do I get 9v output?

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

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