USB Power Delivery for everyone
USB Power Delivery is a cool standard for getting lots of power—up to 100 W—from a USB Type-C port. Being an open standard for supplying enough power to charge phones, laptops, and just about anything else under the sun, USB PD is poised to greatly reduce the amount of e-waste produced worldwide from obsolete proprietary chargers. Unfortunately, like all USB standards, it’s quite complex, putting it out of reach of the average electronics hobbyist.
PD Buddy Sink solves this problem, letting any hacker or maker use USB PD in their projects. Think of it as a smart power jack. To use it, first configure a voltage and current via the USB configuration interface. Then whenever the Sink is plugged in to a USB PD power supply, it negotiates the power your project needs and provides it on the output connector.
