Questions
How big is the LockNfc3 PCB?
It measures 109 × 64 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LockNfc3 use?
118 parts, built around the IRLML6302, BC817, IRLML9303 and M24C04-BN6. 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 LockNfc3 KiCad files?
From the Kreyl/LockNFC repository on GitHub, at the commit this page was made from: the board is LockNfc_hw/LockNfc3.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LockNfc3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kreyl before reusing the design.
