This is a project that is designed to shove a CM5, a huge battery, and the pi touchscreen into a handheld form-factor. This is meant to help with troubleshooting for audio engineers, although the code is being designed to be very open, allowing you to add your own apps to the launcher and create custom IO Cards

Questions
How big is the Power PCB?
It measures 33 × 45 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Power use?
134 parts, built around the TPS56A37RPAR, BQ25703ARSNR, CSD25402Q3A and CSD17577Q3A. 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 KiCad files?
From the da-penguin-guy/PiPortable repository on GitHub, at the commit this page was made from: the board is PCB/Power/Power.kicad_pcb and its schematic PCB/MainBoard/8Mux.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power design in my own project?
Its repository states no licence, so its author keeps all rights: ask da-penguin-guy before reusing the design.
