A generic eeprom programmer using Arduinos. Expected to be used with at28c16, at28c64, at28c256, sst39sf040, m27c512 and others.
Eeprogrammer is an open-source printed circuit board by agsb, from the agsb/eepromgrammer repository on GitHub, published under the CC0-1.0 licence. It is a 2-layer board with 8 parts on 47 nets.
It is built around the 74HC595. Its parts include 4 capacitors and 3 ICs. It belongs with the AVR (ATmega, ATtiny) boards of this library.

8 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.
From the agsb/eepromgrammer repository on GitHub, at the commit this page was made from: the board is kicad/eeprogrammer.kicad_pcb and its schematic kicad-older/eepromgramer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
