Eeprom programmer for Arduino Mega PCB (Only PCB, no parts) You can find all the software (Windows & Arduino sourceode) on the project page: https://www.qcontinuum.org/eeprom-programmer This hardware and software project reads and writes 28-pin EEPROMs (such as 28C64, 28C128, etc.) using an Arduino Mega and a Windows PC. It is based on the Arduino Mega Flash Programmer project by Eric M. Klaus. All the components to build this project are also available in this webshop. This is what the complete build circuit looks like:
