Questions
How big is the Isp PCB?
It measures 26.7 × 20.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Isp use?
24 parts, built around the ATTINY841-SSU. 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 captdam/AVR441ISP repository on GitHub, at the commit this page was made from: the board is isp/PCB/isp.kicad_pcb and its schematic isp/PCB/isp.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 states no licence, so its author keeps all rights: ask captdam before reusing the design.
