![]() Besides, you can set the IIC address by resistance adjustment. ![]() It is smaller and keeps EEPROM 4KB ROM to record information related to alarm clocks and events. The module is powered by single cell CR1220 (service life: 3~5 years). ![]() The test conducted shows the time error is only about 1 second in 24 hours (the average time error of Mechanical Watches is about 20s). The new version DS1307 RTC module adopts high precision crystal oscillator which reduces time error dramatically. It is cheap and affordable in most applications such as time clock, data logger, etc. Gravity I2C DS1307 RTC module is a easy-to-use Real Time Clock module. It comes with a Gravity IIC interface, and the size is also reduced to fit miniaturization application. Gravity_I2C_DS1307_RTC_Module_SKU_DFR0151-DFRobotĪfter several months "Out of Stock", DS1307 RTC module has a big upgrade.
