Questions
How big is the Star Tracker PCB?
It measures 76.2 × 42.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Star Tracker use?
34 parts, built around the ATSAMD21E18A-AU and DRV8833PW. 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 Star Tracker KiCad files?
From the MichaelRyanGreer/Star_Tracker repository on GitHub, at the commit this page was made from: the board is PCB/Star Tracker.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Star Tracker design in my own project?
Its repository states no licence, so its author keeps all rights: ask MichaelRyanGreer before reusing the design.
