The eepromBUG is a handy little device that enables you to store 128 Kbits (16K byte) worth of program data in non-volatile RAM. Based around the popular 24LC128, it's a low power device offering a page write time of 5ms with more than a million erase and write cycles available. Data retention without any power is greater than 200 years. Selectable addressing modes means you can use up to four eepromBUGs at any given time.
This is a quarter size stickyBUG and occupies one quarter of a stickySHIELD. This means you can have four quarter size bugs per shield or you can have one half size BUG and two quarter size BUGs per shield. They can be stacked on other stickySHIELDs if required.
