DS1307 Clock Module DC 5V I2C IIC RTC AT24C32 Real Time Clock Module For AVR ARM PIC For Arduino Without Battery

Introduction

Working voltage: DC5v

Function Description:

1. Adopt LIR2032 rechargeable lithium battery with charging circuit to solve the problem that DS1307 cannot read or write with spare battery. After fully charged, it can provide DS1307 timekeeping for 1 year.

2. Lead out the clock foot of DS13O7 to provide the clock signal for the microcontroller. 3. Other 120 devices can be cascaded.

Features:

1. It can count the seconds, hours, minutes, days of the month, month, and days of the week, and has a leap year compensation function. The annual limit is 2100.

2. 56 bytes of non-lost RAMo

3. Automatic power failure detection and switching circuit.
