Questions
How big is the Pi hat PCB?
It measures 65 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pi hat use?
18 parts. 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 Pi hat KiCad files?
From the ComputerScienceHouse/bits-n-bytes-PCB repository on GitHub, at the commit this page was made from: the board is pi-hat/pi-hat.kicad_pcb and its schematic jetson-hat/jetson-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pi hat design in my own project?
Its repository states no licence, so its author keeps all rights: ask ComputerScienceHouse before reusing the design.
