Questions
How big is the Combined PCB?
It measures 94 × 119.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Combined use?
19 parts, built around the ATMEGA168PA-MU, ATGM336H-5N31, RA-08H(915) and AP9101CK-AHTRG1. 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 Combined KiCad files?
From the neatstranger/pal-collar repository on GitHub, at the commit this page was made from: the board is Combined/Combined.kicad_pcb and its schematic Combined/Combined.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Combined design in my own project?
Its repository states no licence, so its author keeps all rights: ask neatstranger before reusing the design.
