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.
EEPROM stands for electrically erasable programmable read-only memory. It is a secondary storage device that once written (programmed) can hold data even when the power is removed. If you need more storage for your project, or you want to learn how to use EEPROM, then this module is designed for you. It supplies an extra 256k byte for your project. You only need simply wire them via I2C.
