Questions
How big is the PiHat PCB?
It measures 65 × 29.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PiHat use?
65 parts, built around the STM32F031G4U6 and LSM6DS33. 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 PiHat KiCad files?
From the mkramar/dizzyrobot repository on GitHub, at the commit this page was made from: the board is Schamatic/PiHat/PiHat.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PiHat design in my own project?
Its repository states no licence, so its author keeps all rights: ask mkramar before reusing the design.
