Questions
How big is the Wireslesslock PCB?
It measures 50 × 50 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Wireslesslock use?
69 parts, built around the ESP32-S3-WROOM-1-N8, SIM68M, TPS55340RTER and TPS63020DSJR. 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 Wireslesslock KiCad files?
From the Shehroz30/wireslesslock repository on GitHub, at the commit this page was made from: the board is wireslesslock.kicad_pcb and its schematic power.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wireslesslock design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
