Originally the Arduino RTC / EEPROM shield was going to be incorporated into a single board for an aquarium controller, but since none of these boards exist (to my knowledge) I decided to break them up into shields which you can use.

Overview

Demo:

Features:

• 1 DS1307 RTC chip
• 2 32kb EEPROM chips

Since both of these items run on the I2C bus it only uses 2 analog pins on the Arduino (plus power and ground). This has a stackable format if you use double high headers as well.

The EEPROM chips are addressable and the address pins are pinned out so you can jumper them. This would allow you to have up to 3 shields of EEPROM chips (192kb of storage).

Once the eagle files are cleaned up they will be available for download here.
