Most breadboard power supplies use a DC barrel jack or USB mini connectors. But let’s be honest, most of our workbenches are now equipped with USB C power supplies which can offer a lot of benefits. In this video Zach updates and improves his old breadboard power supply with a new PCB that uses USB C power delivery. This means he can select voltages between 3.3V, 5V, 9V, 12V, 15V, and 20V on each rail of the breadboard.

Brilliant. This should be a product you sell on DigiKey!

@joshuaoduroadu5376 Ай бұрын

I agree 💯%

resetable fuse would be cool to have

@JonathanRansom Ай бұрын

Let's see a v2! I love watching people improve version 1s.

@ArnaudMEURET Ай бұрын

The v2 will have a voltage selector harder to switch by mistake!

@DoctorX17 Ай бұрын

Having a selector switch for each side would be cool. Havng a display that shows the voltage, power consumption per rail, and total power consumption would also be really neat

@gblargg Ай бұрын

USB PD only allows one voltage. The point of this design is to leverage PD voltage regulation.

Shut UP and take my money!

@grhinson Ай бұрын

Knowing me I would knock the switch and fry my circuit

@whited250 Ай бұрын

I like the concept a lot! I would be worried about bumping that voltage selector and frying something by accident though 🙂

@jyvben1520 Ай бұрын

have the pcb upside down, so only the board skims over the top of the breadboard to plugin the pins, all the electronics on the underside, adding the microcontroller also lets you dump the selector, a few buttons up/down and ... might be enough and a ledbar, that would need 2 part pcb, lower for electronics, upper for pins, make lower have output twice (side A +/-, side B -/+), so you can choose on which side to connect the upper board, soldered or flexible wires/ribbon, if possible have 3 usb c spaces on lower for 1 connector => top, middle, bottom.

I really want to buy this, especially with the optimizations you described, switches instead of jumpers, a screen, and even a resettable fuse!

@HyperMakes Ай бұрын

Actually good ideation. Eager for the V2, if its ever going to be done or released.

@gblargg Ай бұрын

GND should be the outside rails on either side. This avoids orientation issues and makes it the same layout on either side. Voltage selection should be a button that must be held for a while to unlock. A switch that you can bump and overload your circuit isn't good. An on-board voltage regulator would be good as many USB supplies have significant ripple (100+ mV p-p) and output a higher voltage than stated.

Great suggestions. Unfortunately whoever made breadboards didn't think to put the GND rails on the outside. They have markings that are color coded to indicate positive and negative rails.

@johnglielmi6428 Ай бұрын

I'd buy a boatload of those. I have the same issue of the supplies being unstable and blocking a lot of the connection rails.

@alpantone Ай бұрын

No way, I just designed and ordered a very similar PCB! I was having the same problem getting power conveniently on a breadboard, so I made the same C-shaped board. I just have a plug going to the power supply of my synthesizer, so mine is way simpler and only does +12v, -12v, and ground, but I also put in spots to solder optional headphone jacks or potentiometers.

@aaronnowack3637 Ай бұрын

One thing i often see missing are dual supplies, having positive and negative selectable voltages would be great

@bytesizedengineering 28 күн бұрын

That's a good suggestion

@aaronnowack3637 28 күн бұрын

@@bytesizedengineering Thanks, it would be helpful for the weird analog electronics people (such as myself ;) ). Something with atleast - 5/+5V and +3.3V, but selectable rails (don't need to be independent, just +/- 3.3, +/-5, +/- 9, +/- 12) and the 3.3v connection would be awesome! I do analog + digital stuff, and need the +/- supply with ground referenced to the usb connection to use other connected devices as well. Using the analog discovery 3 to do +/- 5V currently, but it doesn't have that third 3.3V connection.

cool Project. Does your board get hot when boosting power to 20V?

Awesome circuit Zach! When are you putting it on Kickstarter?

@bytesizedengineering Ай бұрын

Do you think there is a market for this? I have always wanted to run my own kickstarter for something.

@danielmatthews8475 Ай бұрын

@@bytesizedengineering I'm not a a marketing guy, but I'd definitely buy one! (or more) if you are thinking of the next version, a nice thing to have would be a separate power switch on the outputs and LEDs on the output lines. I'm constantly turning breadboards on and off to rewire them - mostly because they never work the first time. And being able to at a glance tell if the power is available (on the USB side) and powering the bread board (on the circuit side) can save a lot of the magic smoke from getting out.

Nice project. What is the max current that can be supplied at each available voltage setting?

@gblargg Ай бұрын

USB PD typically supplies 3A or so maximum.

@bytesizedengineering Ай бұрын

@mobilered2776 Ай бұрын

Good idea, but what is the max current in output?

@bytesizedengineering Ай бұрын

5A max current

Are ALL USB-C power supllies capable of giving ALL voltages? What happens, if the power supply can not supply the chosen voltage?

@bytesizedengineering Ай бұрын

No, a USB C power delivery or "PD" supply is needed. Link is in the description

@thiloreichelt4199 Ай бұрын

@@bytesizedengineering Ok, my failure. I meant: are ALL PD power supplies required to produce ALL voltages up to 20V? Eg, my smartphone goes only up to 9V according to one of these Chinese PD monitors. The power supply it came with might be limited to 9V.
