A PD Buddy Sink designed for automated assembly!
- Sizes of passives reduced from 0805 to 0402, with a few 0603 passives as well
- Surface-mount USB connector instead of hybrid (don't worry, the new connector's shield still has through-hole pins for mechanical strength)
- QFN microcontroller instead of QFP
- Boot switch and programming header moved to bottom of board
- Board size greatly reduced (48 mm × 26 mm ⇒ 30 mm × 25 mm)
- Screw hole spacing changed (18 mm ⇒ 17 mm)
- To accommodate the tighter packing of components, the board now has four layers instead of two
Additionally, a programming jig has been designed to accommodate programming the Sink without a boot switch or programming header installed. The PCB can be found in the programming-jig directory, and a 3D-printed spacer can be found in the pd-buddy-openscad repository.
