EEPROM memory module from Adafruit.What is EEPROM memory?
Under the abbreviation EEPROM stands for electrically erasable programmable read-only memory , or non-volatile digital memory. Its task is to store data that are relevant to the microcontroller. A characteristic feature of this type of memory is storing data even after power failure. Number of writes and deletes of data on EEPROM is limited, while the number of reads is infinite. In addition, the process of writing or overwriting can also apply to a single byte.
In our offer you will also find other modules with EEPROM memory. We invite you to familiarize yourself with the available range.
