Questions
How big is the Main pcb PCB?
It measures 100 × 60 mm and has 2 copper layers, 0.8 mm thick.
What parts does the Main pcb use?
109 parts, built around the RP2040, DS4424N+, W25Q128JVSIQ and MIC5233YM5-TR. 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 Main pcb KiCad files?
From the zephray/Preader repository on GitHub, at the commit this page was made from: the board is hardware/main_pcb/pcb.kicad_pcb and its schematic hardware/front_pcb/front_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Main pcb 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).
