Questions
How big is the CxCat PCB?
It measures 55 × 106 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CxCat use?
54 parts, built around the ATMEGA8A-PU, L293D, 74HC595 and L7805. 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 CxCat KiCad files?
From the CixoDevelop/CxCat repository on GitHub, at the commit this page was made from: the board is schematic/CxCat/CxCat.kicad_pcb and its schematic schematic/CxCat/CxCat.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CxCat design in my own project?
Its repository states no licence, so its author keeps all rights: ask CixoDevelop before reusing the design.
