AT24C02 Module I2C IIC Interface EEPROM Memory Module

The AT24C02 Module is a compact non volatile EEPROM memory board designed for serial data storage using the I2C IIC communication protocol. It is based on the AT24C02 2K bit EEPROM device and provides reliable byte level read and write operations for embedded systems.

This module is suitable for storing configuration parameters calibration data device IDs and small data logs in microcontroller based projects. The I2C interface allows easy integration with Arduino STM32 and other development platforms.
