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