Questions
How big is the Pcbcax PCB?
It measures 62 × 60.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Pcbcax use?
58 parts, built around the ATMEGA328P-AU, CH340C, L293D and AMS1117-5.0. 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 Pcbcax KiCad files?
From the 7bwiiza/Robot-creation repository on GitHub, at the commit this page was made from: the board is pcbcax.kicad_pcb and its schematic pcbcax.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pcbcax design in my own project?
Its repository states no licence, so its author keeps all rights: ask 7bwiiza before reusing the design.
