Questions
How big is the Programmer PCB?
It measures 99.1 × 76.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Programmer use?
10 parts, built around the 74HC273D. 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 Programmer KiCad files?
From the agranlund/raven repository on GitHub, at the commit this page was made from: the board is hw/simm/programmer/programmer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Programmer design in my own project?
Its repository states no licence, so its author keeps all rights: ask agranlund before reusing the design.
