Questions
How big is the Projekt1 PCB?
It measures 184.6 × 41.6 mm and has 2 copper layers, 1.59 mm thick.
What parts does the Projekt1 use?
72 parts, built around the ESP-12E, LTV-824, MMBT3904 and ABM3-8.000MHZ-D2Y-T. 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 Projekt1 KiCad files?
From the Now4czyk/access_control_circuit repository on GitHub, at the commit this page was made from: the board is projekt1.kicad_pcb and its schematic projekt1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Projekt1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Now4czyk before reusing the design.
