Questions
How big is the USBasp PCB?
It measures 77 × 53.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the USBasp use?
30 parts, built around the ATMEGA8-16PC. 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 KiCad files?
From the poly-electronics/utilPCB repository on GitHub, at the commit this page was made from: the board is USBasp/USBasp.kicad_pcb and its schematic Amplifier150w/amplifier150w.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the USBasp design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
