USB-C Power Supply kit

This kit for the USB-C Power Supply includes just about everything you need to build it:

The two PCBs
The two programmed microcontrollers
The pre-assembled USB-PPS module
The case
All other parts that go on both PCBs
Hardware

You just need to add some solder and perhaps some wire and connectors, depending on how you plan to configure the supply.
