This is AT24C256 Serial EEPROM I2C IIC Interface Data Storage Module for Arduino. If you need to do some data storage in Arduino, then using the EEPROM is probably the most simple practices. In actual, Arduino used ATmega chip itself has certain EEPROM memory, but only a limited number.
We design the external EEPROM memory module which use I2C bus line to connect with Arduino, and with the pluggable chip, insert in this series, so it will easy to expand capacity, basically just need to insert a bigger capacity of EEPROM chip. The storage module is based on EEPROM chips of AT24C series, 256K bit capacity, that’s 32k bytes. The EEPROM module communicates with Arduino through the I2C interface. It will be better to use with Arduino-Sensor-Shield-V4.0 and the Arduino-I2C-COM-Cable.
