Questions
How big is the Print PCB?
It measures 12 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Print use?
38 parts, built around the ATTINY85-20SU, CH340C, WS2812B and PRTR5V0U2X. 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 Print KiCad files?
From the MonkeyEnterprise/do-not-disturb-indicator repository on GitHub, at the commit this page was made from: the board is pcb/print.kicad_pcb and its schematic pcb/print.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Print design in my own project?
Its repository states no licence, so its author keeps all rights: ask MonkeyEnterprise before reusing the design.
