Questions
What parts does the USBasp v1 use?
21 parts, built around the ATMEGA328-PU. 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 USBasp v1 KiCad files?
From the akruby/USBasp_v1 repository on GitHub, at the commit this page was made from: the board is usbasp_v1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the USBasp v1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask akruby before reusing the design.
