Questions
How big is the Lutje v1 PCB?
It measures 19 × 24.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Lutje v1 use?
46 parts, built around the ESP32-C3, E28-2G4M12S, TLV76733DRVR and BAT60A. 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 Lutje v1 KiCad files?
From the WRusman/Lutje repository on GitHub, at the commit this page was made from: the board is Lutje v1.kicad_pcb and its schematic Lutje v1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lutje v1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask WRusman before reusing the design.
