DFRobot Gravity: module with EEPROM memory - I2C - 256kB

Module EEPROM from series Gravity, allows for memory expansion on the data with 256 KB in Arduino - based on the system24LC256 from Microchip Techonogy Inc. It communicates through interfaceI2S, it is powered by voltage from2.5 V to 5.5 V. The EEPROM is characterized by almost infinite number of read cycles, and very low energy consumption.Data is saved also after power-off.The kit also includes a cable suitable forGravity DFRobot IO Expansion Shield.

The system has four pins on a special connector to which the cable is included in the package.
