Incase that wasn't obvious haha. Here is a repository of a bunch of PCB's I've made, from a heart lightboard for your lover (It works) to lampnodes that connect to a central server!

Questions
What parts does the Eeprom use?
8 parts, built around the CH341A. 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 Eeprom KiCad files?
From the SaltyMelonYT/PCB-Projects repository on GitHub, at the commit this page was made from: the board is Programmer/eeprom/eeprom.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Eeprom design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
