EEPROM

- This module uses the domestic AT24C02 chip (mall number: [C356696](https://item.szlcsc.com/331802.html)), and the internal storage space is 256X8 to provide 2048-bit serial electrically erasable programmable read-only Each byte of 256 in memory is 8 bits. The device is optimized for many industrial and commercial applications where low power consumption and low voltage operation are critical.
