Questions
How big is the PCBProject PCB?
It measures 38.1 × 133.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PCBProject use?
85 parts, built around the RP2040, SN74LV1T34DBV, W25Q32JVSSIQ and AMS1117-3.3. 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 PCBProject KiCad files?
From the vinnesttree/TixClock repository on GitHub, at the commit this page was made from: the board is PCB/PCBProject.kicad_pcb and its schematic PCB/PCBProject.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCBProject 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).
