Questions

How big is the ISS tracker PCB PCB?

It measures 81.8 × 55.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the ISS tracker PCB use?

14 parts, built around the IRF540N. 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 ISS tracker PCB KiCad files?

From the WillDoesBuild/ISS-tracker repository on GitHub, at the commit this page was made from: the board is PCB files/ISS tracker PCB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the ISS tracker PCB design in my own project?

Its repository states no licence, so its author keeps all rights: ask WillDoesBuild before reusing the design.
