Questions
How big is the Isp PCB?
It measures 52.6 × 31.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Isp use?
6 parts. 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 Isp KiCad files?
From the HWXLR8/pcbeef repository on GitHub, at the commit this page was made from: the board is isp/isp.kicad_pcb and its schematic ataxx2jamma/ataxx2jamma.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Isp 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).
