Questions
How big is the GPS Compass Arrow PCB?
It measures 90.8 × 73.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the GPS Compass Arrow use?
156 parts, built around the MAX7219M, 74VHC9595FT and FFC2B28-12-G. 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 GPS Compass Arrow KiCad files?
From the bismarx-v1/GPS-Compass repository on GitHub, at the commit this page was made from: the board is _electrical/GPS-Compass_Arrow/GPS-Compass_Arrow.kicad_pcb and its schematic _electrical/GPS-Compass/GPS-Compass.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the GPS Compass Arrow design in my own project?
Its repository states no licence, so its author keeps all rights: ask bismarx-v1 before reusing the design.
