Questions
How big is the OpenHarrierUFC PCB?
It measures 144 × 158 mm and has 2 copper layers, 1.6 mm thick.
What parts does the OpenHarrierUFC use?
92 parts, built around the HT16K33-28SOP. 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 OpenHarrierUFC KiCad files?
From the OpenHarrier/AV8B-NA repository on GitHub, at the commit this page was made from: the board is UFC/PCB/OpenHarrierUFC/OpenHarrierUFC.kicad_pcb and its schematic OfficialOpenHarrierModel/PCB/OH-UFC-Simple/OH-UFC-Simple/OH-UFC-Simple.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the OpenHarrierUFC design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
