Tiny I2C DS1307 Clock RTC Module for Arduino without Battery

Tiny I2C DS1307 Clock RTC Module for Arduino without Battery

Features:

• DS1307 is a low power consumption, full BCD code clock calendar real-time clock chip with 56-byte nonvolatile RAM

• The address and data are transmitted through a two-wire bidirectional serial bus

• The chip can provide seconds, minutes, hours, and other information, and the days of each month can be automatically adjusted

• It also has the function of leap-year compensation

• The AM/PM flag determines whether the clock works in the 24-hour or 12-hour mode

• The chip has a built-in power-sensing circuit with power failure detection and battery-switching functions

• It can count seconds, hours, minutes, days of each month, months and days of each week, and has the leap year compensation function

• Programmable square wave output

• Automatic power down detection and switching circuit In battery backup mode, the power consumption is less than 500nA

Package includes:

• 1 x Module
