Description
AT24C02 I2C EEPROM Memory Storage Module Data Storage
The I2C Interface EEPROM Memory Module with AT24C02 is a compact and reliable solution for expanding the storage capacity of microcontroller-based projects. While Arduino boards, such as the Arduino Uno, come with built-in EEPROM for data storage, they often have limited space—typically around 512 bytes. This may not always be sufficient for applications requiring persistent storage of settings, sensor logs, or other critical data. Additionally, EEPROM has a limited write cycle lifespan, which can lead to degradation over time.The AT24C02 EEPROM chip provides an efficient alternative, offering 2048 bits (256 bytes) of non-volatile memory. It retains data even when the power is turned off, ensuring long-term storage of important information. Communicating via the I2C interface, it is easy to integrate with microcontrollers, and standard libraries are available for immediate use, simplifying implementation. This module is ideal for projects where 512 bytes is too little, but an SD card (with gigabytes of space) is excessive. It strikes the perfect balance for storing small amounts of essential data, such as calibration parameters, user preferences, or temporary logs, making it an excellent choice for embedded systems and IoT applications.

Customer Reviews
It's tiny and works well. It would have been better if the i2c and power pins where not soldered already it would be better to have them stick out on the bottom of the board so it works in a breadboard right side up.
Works as advertised. Used the Aardvark pod and software to program the device.
Works, Great Product, Highly Recommend
Have not installed product, so not tested.
Works perfectly no problems finding code to work and play around with,reading and writing to the chip sectors,great for adding extra memory to micro controllers,and can easily be removed from the DIP seat for connection to your own circuits.
