Here is a shield, schematics, and source for a shield based on Microchip 25AA1024 (128k bytes) flash EEPROM.
The 24AA1025 is an I2C chip, but the link points to code for a 25AA1024 SPI chip. Typo? Wrong link? Or did I read it wrong?
Lurch - that was a typo. Good catch. I will fix the original post.
