Questions
How big is the Satellite Arduino controller PCB?
It measures 97 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Satellite Arduino controller use?
27 parts, built around the A4988. 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 Satellite Arduino controller KiCad files?
From the grinje/AutoSatTracker repository on GitHub, at the commit this page was made from: the board is Satellite_Arduino_controller/Satellite_Arduino_controller.kicad_pcb and its schematic Satellite_Arduino_controller/Satellite_Arduino_controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Satellite Arduino controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask grinje before reusing the design.
