Description

AT24C256 256Kb memory interface

If you need some memory in Arduino projects and the EEPROM in the ATmega chip is too limited, this I2C EEPROM module is the best choice. It is based on the AT24C256 EEPROM chip with a capacity of 256 Kb. Communicates with Arduino via I2C bus, facilitates much easier data storage and enhances Arduino’s design capabilities.
