Questions
How big is the ISARPiv2 PCB?
It measures 81.3 × 33.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ISARPiv2 use?
12 parts, built around the ACH-14.31818MHZ-EK. 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 ISARPiv2 KiCad files?
From the eigenco/RPiISA repository on GitHub, at the commit this page was made from: the board is ISARPiv2/ISARPiv2.kicad_pcb and its schematic 20231105-PCBv2/RPI2ISA.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ISARPiv2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask eigenco before reusing the design.
