Questions

How big is the Palprom PCB?

It measures 21.6 × 36.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Palprom use?

5 parts, built around the 27C256-17/J. 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 Palprom KiCad files?

From the hoglet67/palprom repository on GitHub, at the commit this page was made from: the board is kicad/palprom.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Palprom design in my own project?

Its repository states no licence, so its author keeps all rights: ask hoglet67 before reusing the design.
