Questions
How big is the RPi Hat PCB?
It measures 65 × 56.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RPi Hat use?
86 parts, built around the ATTINY1634-SU, DMMT5401, DMP3056L-7 and BC846BPDW1. 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 RPi Hat KiCad files?
From the Blake-Robotics/PiUPS repository on GitHub, at the commit this page was made from: the board is hardware/RPi_Hat.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the RPi Hat design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
