If you need to do some data storage in Arduino but found that the EEPROM in ATmega chip too limited, then this Crowbits-EEPROM is your best choice.

 

 

How does it work?

The erasing function of EEPROM does not need the help of other devices, it is based on electronic signal to modify its content, and it is the minimum modification unit by Byte, not bound to wash all the information can be written, completely getting rid of the shackles of EPROM Eraser and programmer. EEPROM still needs to use a certain programming voltage when writing data. At this time, it can be easily rewritten by using a special refresh program provided by the manufacturer, so it belongs to a dual-voltage chip. With the help of the dual-voltage characteristics of the EEPROM chip, the BIOS has a good anti-virus function. During the upgrade, the jumper switch is turned to the " on " position, that is, the chip is added with the corresponding programming voltage, and it can be easily upgraded; In normal use, turn the jumper switch to the " off " position to prevent illegal modification of the BIOS chip by CIH viruses.

 

 

How to use it?

Data is written to the EEPROM by the master controller through the IIC interface, and it can keep the data from being lost after power off.
