Build information for my DIY SST39SF0x0 FLASH programmer. Program FLASH EEPROMs from Scratch in less than 20 minutes. See my YouTube channel https://www.youtube.com/channel/UCXYQcMpUBT3aaQKfmAVJNow for more information.
Version: Hardware 1.1 / Software 2.1
NEW: I've included a PCB version (schematics and Gerber files) of the breadboard hardware and upgraded the software. Now you can write any file size <= 512KB with fully automated data transmission and verification. No need to edit file sizes in the Arduino sketch any more.
Have fun!
