This is a simple 28C256 EEPROM programmer PCB I made and manufactured in 2024 via JLCPCB.
Sadly the original KiCAD files were lost, only the gerber is available, although it's ready for manufacture.
The used components are:
- 1x Arduino Nano
- 2x 74HC595 shift register
- 1x 28-pin DIP ZIF socket
The whole PCB was rounded by hand as an aesthetic choice.
This programmer runs a modified version of the TommyPROM firmware, to use 74xx595 shift registers instead of 74x164 ones.
