DS3231SN RTC Module, Aideepen 2PCS DS3231 AT24C32 IIC High Precision Real Time Clock Breakout Replace DS1307 for Arduino

#ad
Aideepen #ad - Thanks for your understanding. 24c32 addresses can be shorted A0/A1/A2 modify default address is 0x57. Iic bus interface, the maximum transmission speed of 400khz working voltage of 5V, cascaded with other IIC device. For battery model, you can choose cr2032 or you can use a rechargeable CR2025, LIR2032.

Please must note:because it's not safty to ship the li battery via air mail, our ds3231 RTC Modules don't include battery. Rtc maintains seconds, and year information. Save time and high precision addition. 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. Ds3231 rtc module also has some other features that extend the system host of additional features and a range of options.

Less than 31 days of the month, minutes, hours, the end date will be automatically adjusted, day, date, month, including corrections for leap year. The clock operates in either the 24 hours or band / AM / PM indication of the 12-hour format. The device integrates a very precise digital temperature sensor, through the I2C * interface to access it at the same time. Chip temperature sensor comes with an accuracy of ± 3°C.

Diymore DS3231 DS3231SN AT24C32 High Precision IIC RTC Module Real Clock Timer Memory Board Beats DS1307 for Arduino Without CR2032 Battery

#ad
diymore #ad - The device incorporates a battery input, and maintains accurate timekeeping when main power to the device is interrupted. The ds3231sn is a low-cost, extremely accurate I2C real-time clock RTC with an integrated temperature-compensated crystal oscillator TCXO and crystal.

Address and data are transferred serially through an I2C bidirectional bus. The date at the end of the month is automatically adjusted for months with fewer than 31 days, day, month, minutes, hours, including corrections for leap year. There is only one minute of error in a year. The integration of the crystal resonator enhances the long-term accuracy of the device as well as reduces the piece-part count in a manufacturing line. Two programmable time-of-day alarms and a programmable square-wave output are provided. The rtc maintains seconds, date, and year information.
