EEPROM Storage Module w/ I2C Interface - AT24C256

You’ve always wanted to output analog voltages from a microcontroller, the MCP4725 is the DAC that will let you do it! The MCP4725 is an I2C controlled Digital-to-Analog converter (DAC). A DAC allows you to send analog signal, such as a sine wave, from a digital source, such as the I2C interface on the Arduino microcontroller. Digital to analog converters are great for sound generation, musical instruments, and many other creative projects!

If you need to do some data storage in Arduino but found that the EEPROM in ATmega chip too limited, then this I2C EEPROM module is your best choice. This module is based on the EEPROM chip AT24C256, which has 256k bit capacity. It communicate with Arduino with I2C bus, helps you do much more data storage easily.
