Real Time Clock (RTC) DS1307 I2C Clock module

Description Real Time Clock (RTC) DS1307 I2C Clock Module

The Real Time Clock (RTC) DS1307 I2C Clock Module is a compact time management solution. This product is built around the DS1307 chip. This chip is known for its reliability in time registration. The unique thing about this module is the support of the I2C protocol. This makes integration with various microcontrollers, such as Arduino, easy. The module works on a Lithium button cell battery. This type of battery guarantees a long lifespan. The RTC module keeps track of time even when power is disconnected from the microcontroller.

The functions of this clock module are diverse. It displays seconds, minutes, hours, days, dates, months and years. An important feature is the automatic adjustment to months with less than 31 days. It also takes leap years into account. The module works in both 24-hour and 12-hour formats. These formats have AM/PM indication. Please note: the battery is not included. Images with battery are for illustrative purposes only of the product in use.
