Questions
How big is the M16rf PCB?
It measures 209.5 × 125.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the M16rf use?
55 parts, built around the 74LS125DC, 74LS04PC, 74LS00SC and 74LS02PC. 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 M16rf KiCad files?
From the rcapaverde/cubo repository on GitHub, at the commit this page was made from: the board is pcb_v3/m16rf/m16rf.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the M16rf design in my own project?
Its repository states no licence, so its author keeps all rights: ask rcapaverde before reusing the design.
