Questions
How big is the RFID Reader PCB?
It measures 57.9 × 48 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RFID Reader use?
17 parts, built around the WEMOS D1 MINI. 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 Reader KiCad files?
From the Hasenpups/Wifi_RFID_Reader repository on GitHub, at the commit this page was made from: the board is RFID_Reader.kicad_pcb and its schematic RFID_Reader.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RFID Reader design in my own project?
Its repository states no licence, so its author keeps all rights: ask Hasenpups before reusing the design.
