Questions
How big is the EEPROMBoard PCB?
It measures 98.8 × 69.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EEPROMBoard use?
10 parts, built around the ATTINY2313V-10PU and 74HC595. 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 EEPROMBoard KiCad files?
From the okoz/electronics repository on GitHub, at the commit this page was made from: the board is eeprom-programmer/hardware/EEPROMBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the EEPROMBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask okoz before reusing the design.
