Questions
How big is the DSPic Pi Hat PCB?
It measures 65 × 66.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DSPic Pi Hat use?
93 parts, built around the FT230XS-R and WS2812B. 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 DSPic Pi Hat KiCad files?
From the NortheasternSatelliteLab/DSPic_Pi_Hat repository on GitHub, at the commit this page was made from: the board is DSPicPiHat/DSPicPiHat.kicad_pcb and its schematic DSPicPiHat/DSPicPiHat.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DSPic Pi Hat design in my own project?
Its repository publishes it under the CERN-OHL-S-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).
