Questions
How big is the Power processing unit PCB?
It measures 99.3 × 95.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power processing unit use?
80 parts, built around the PIC18F56Q71-I/PT, TPS61288RQQR, AZ1117CH2-3.3TRG1 and DR127-3R3-R. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Power processing unit KiCad files?
From the ear0/ECE445_Team18 repository on GitHub, at the commit this page was made from: the board is hardware/pcb/power_processing_unit/power_processing_unit.kicad_pcb and its schematic hardware/pcb/IFBoard/IFBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power processing unit design in my own project?
Its repository states no licence, so its author keeps all rights: ask ear0 before reusing the design.
