USB-C is awesome. I showed that during several previous videos. But I was missing out on 1 feature that USB-C also offers. PPS! Or Programmable Power Supply. By using that you can basically turn your USB-C power source into a variable power supply with adjustable voltage, current limit and much much more. So how easy is that to use and how well does it work? Let's find out!
