Questions
What parts does the Pcb1 v2 use?
53 parts, built around the 74AHC1G14GV, LTV-358T, LM1117-3.3 and LM7805CT. 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 Pcb1 v2 KiCad files?
From the kristophertab/pcb_robot repository on GitHub, at the commit this page was made from: the board is pcb1_v2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pcb1 v2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask kristophertab before reusing the design.
