Questions
How big is the Sattrack PCB?
It measures 49.2 × 65.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sattrack use?
17 parts. 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 Sattrack KiCad files?
From the ZonkSec/sattrack repository on GitHub, at the commit this page was made from: the board is hardware/sattrack/sattrack.kicad_pcb and its schematic hardware/sattrack/sattrack.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sattrack design in my own project?
Its repository states no licence, so its author keeps all rights: ask ZonkSec before reusing the design.
