Overview

This module contains a real-time clock, an EEPROM and a temperature sensor module, making it ideal for weather monitoring applications.

The DS1307 real-time clock chip features 56 bytes of non-volatile RAM, full BCD code clock, and a calendar.

The AT242Cxx chip is an I2C EEPROM optimized for low power and small footprint applications.

The DS18B20 digital temperature sensor uses a single wire communication interface, which makes it easy to interface it with low pin count microcontrollers.
