EEPROM programmer based on Arduino
This repository contains Kicad schematics and .ino source files to build the EEPROM programmer using Arduino UNO R3. If you are following the Ben's Eater course to build a 6502 computer, you will see that Ben uses a TL866 II Plus model, but it is possible to program memory chips using this homebrew board.

Questions
How big is the Eeprom programmer PCB?
It measures 109.2 × 78.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Eeprom programmer use?
19 parts, built around the 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 Eeprom programmer KiCad files?
From the mtojek/eeprom-programmer repository on GitHub, at the commit this page was made from: the board is kicad/eeprom-programmer/eeprom-programmer.kicad_pcb and its schematic kicad/eeprom-programmer/eeprom-programmer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Eeprom programmer design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
