#adAideepen #ad - Save time and high precision addition. Thanks for your understanding. Rtc maintains seconds, the end date will be automatically adjusted, month, day, and year information. Less than 31 days of the month, minutes, date, hours, including corrections for leap year.

Iic bus interface, the maximum transmission speed of 400khz working voltage of 5V, cascaded with other IIC device. Chip temperature sensor comes with an accuracy of ± 3°C. Upgraded ds3231sn chip, acurate time keeping, not ds3231"m"the ds3231sn is the tcxO high stability RTC, accurate I2C real-time clock RTC module with a temperature-compensated crystal oscillator TCXO improving long-term accuracy. Please must note:because it's not safty to ship the li battery via air mail, our ds3231 RTC Modules don't include battery.

The clock operates in either the 24 hours or band / AM / PM indication of the 12-hour format. For battery model, you can choose cr2032 or you can use a rechargeable CR2025, LIR2032. 24c32 addresses can be shorted A0/A1/A2 modify default address is 0x57. Ds3231 rtc module also has some other features that extend the system host of additional features and a range of options. The device integrates a very precise digital temperature sensor, through the I2C * interface to access it at the same time.
