PD Buddy Sink

This is the circuit board for the PD Buddy Sink, a device which aims to make USB Power Delivery accessible to any electronics hobbyist.

The board is designed for 1 oz copper on all layers. 1.6 mm thickness should be fine. Just keep in mind that it isn’t possible to assemble the board with a soldering iron anymore!

The PCB is made with KiCad, so you’ll need that if you want to make any changes. Several PCB fabricators accept KiCad PCB files directly now, but if you intend to order from one that does not, you’ll need KiCad to plot the Gerbers.

KiCad 4 supports loading footprint libraries from Git repositories, but its support for doing the same with symbol libraries is lacking. To address this, I added the variable _KI_LIB_GIT. Set this path in the main KiCad window (Preferences > Configure Paths) to point to a local copy of the kicad-library repository to ensure that you’re using the latest schematic libraries.
