PD Buddy Sink schematics and circuit board

Clara Hobbs 7ab375f947 4-layer board with smaller components This is a major change! Almost all the components have changed to smaller versions, with 0603 and 0402 passives and a QFN microcontroller. The board now has four layers, with internal layers used for VBUS and GND. The board now measures a mere 25×30 mm! The SWD header and Boot switch footprints have been moved to the bottom to help with this shrinkage. Two test points were added to the bottom as well to make it possible to power the board without using the USB connector. The mounting holes are now slightly smaller (better sized for M3), and only 17 mm apart instead of the old 18 mm. To sum up, everything is smaller and that's almost entirely a good thing, except now it's not really possible to build one by hand.		7 lat temu

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 2 oz copper. It’s probably best to use a 1.0 or 0.8 mm thick PCB to make sure it’s possible to solder the USB connector’s pins.

The PCB is made with KiCad, so you’ll need that if you want to make any changes.
