DS3231 Real Time Clock RTC Module in Pakistan


This is a module made using DS3231 RTC and AT24C32 EEPROM. DS3231 is an extremely accurate, low cost I2C RTC with integrated temperature compensated crystal oscillator. It also has a built in comparator which monitors the status of VCC to detect power failures and to automatically switch to backup power supply. AT24C32 provides 32,768 bits of serial EEPROM organized as 4096 words of 8 bits each. This gives you 32Kb of non-volatile memory for your projects. This module can be easily interfaced with Arduino Boards, Raspberry Pi and all Micro-controllers.





DS3231 Real Time Clock RTC Module in Pakistan High Accuracy DS3231 Precise Real Time Clock Module with 32Kbit EEPROM and a built-in 10-bit temperature sensor having a resolution of 0.25C.The DS3231 .The DS3231 Precise Real Time Clock Module is a low-cost The device incorporates a battery input and maintains accurate timekeeping when main power to the device is interrupted. 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.

DS3231M is an extremely accurate I2C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator.

Save precious cycles on your micro as the RTC maintains seconds, minutes, hours, day, date, month and year information in easy to access registers. On top of that, the DS3231M manages leap years and has two configurable alarm clocks.
