I2C RTC DS1307 AT24C32 Real Time Clock Module For AVR ARM PIC Tiny RTC I2C Modules Memory DS1307 Clock
DS1307 I2C real-time clock chip (RTC) 24C32 32K I2C EEPROM memory
Using LIR2032 rechargeable lithium battery, and with a charging circuit to solve the problem of DS1307 with spare battery can not read and write. After fully charged, it can provide DS1307 timekeeping for 1 year. Small design, 27mm*28mm*8.4mm
Lead out the clock pin of DS1307 to provide the clock signal for the microcontroller. Other I2C devices can be cascaded.
