Every breadboarded electronics project is different, but they all have one thing in common: the need for power. And while many projects require a 5V or 3.3V supply, many require something, or somethings, different. At the end of the day, there’s no one-size-fits-all power solution. Benchtop supplies come close in many situations, but they can be inconvenient to drag to your project location, and typically require mains AC power.
The ProtoV MINI, created by Alex Xia and coming soon on Crowd Supply, plugs into your breadboard to power both rails independently, and is itself supplied by USB-C. It can provide power at up to 20V on each channel, adjustable in 10 mV increments, and has a total power capacity of up to 100W when using a capable USB-C source.
So whether you have access to an adapter plugged into the wall, or a rechargeable power pack, your project is good to go. Even better, it features a credit card-sized footprint, so getting it from place to place is no problem. You could even leave it attached to your favorite breadboard setup so that it’s readily available.
The device runs on Raspberry Pi’s RP2040 chip, and its USB-C connection supports data streaming, allowing you to log your project’s power stats.
ProtoV MINI is open source, so if you want to know more — or even contribute — you can find lots more info here on GitHub.
