Questions
How big is the Rfid PCB?
It measures 100 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rfid use?
41 parts, built around the ATTINY25-20SSU. 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 Rfid KiCad files?
From the hsl25/RFID-PCB repository on GitHub, at the commit this page was made from: the board is rfid.kicad_pcb and its schematic rfid.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rfid design in my own project?
Its repository states no licence, so its author keeps all rights: ask hsl25 before reusing the design.
