Questions
How big is the Pi PCB Hat PCB?
It measures 121.4 × 102 mm and has 4 copper layers, 1.96 mm thick.
What parts does the Pi PCB Hat use?
143 parts, built around the PCA9685PW, SM4002 and ZXMN3A14FTA. 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 PCB Hat KiCad files?
From the CabrilloRoboticsClub/electrical repository on GitHub, at the commit this page was made from: the board is Pi PCB Hat/Pi PCB Hat.kicad_pcb and its schematic Leak_Detection_PCB/Leak_Detection_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pi PCB Hat design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
