Questions
How big is the Lighthouse pcb PCB?
It measures 45 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lighthouse pcb use?
51 parts, built around the ESP32-C3-WROOM-02-H4, CN5711, AP2112K-3.3 and USBLC6-2SC6. 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 Lighthouse pcb KiCad files?
From the MikkoTervala/lighthouse repository on GitHub, at the commit this page was made from: the board is pcb/lighthouse-pcb.kicad_pcb and its schematic pcb/lighthouse-pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lighthouse pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask MikkoTervala before reusing the design.
