Questions
How big is the Cpld PCB?
It measures 105 × 42.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cpld use?
34 parts, built around the AMS1117-3.3 and ECS-TXO-3225-250-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 Cpld KiCad files?
From the RadoslawSajdak/CPLD_PCB repository on GitHub, at the commit this page was made from: the board is cpld.kicad_pcb and its schematic cpld.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cpld design in my own project?
Its repository states no licence, so its author keeps all rights: ask RadoslawSajdak before reusing the design.
