    Add robust storage memory to your TinyDuino with this EEPROM TinyShield.  Built around the Microchip 24FC1025, this EEPROM is a simple way to store settings, logs, or any other data your project needs to keep through power cycles.

    The EEPROM TinyShield is low power and works through the I2C interface. It has 1 Mbit (128KBytes) of storage and is byte addressable.  Example code is provided to make it simple to add EEPROM support to your projects.

      EEPROM TinyShield
      When you have a computer, you can turn it off without losing all of your files and documents. Without this ability to store information, a computer would be much less useful. However, microcontrollers often do not ship with the necessary hardware to store data when power is removed. That's where the EEPROM TinyShield comes in!
