Description
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.
Botland is an official distributor of DFRobot open-source hardware. Every roboticist and practitioner of emerging technology has heard at least once of DFRobot solutions, built above all around Arduino. Our range holds original DFRobot products only.
Example of connecting the module toArduino Uno.
