Questions
How big is the Forschung PCB?
It measures 129.5 × 90.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Forschung use?
53 parts, built around the RFM69HW and BAT42. 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 Forschung KiCad files?
From the francisbuma/PEMSY-Project repository on GitHub, at the commit this page was made from: the board is Forschung.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Forschung design in my own project?
Its repository states no licence, so its author keeps all rights: ask francisbuma before reusing the design.
