DS3231 RTC  is a Precise Real-Time Clock Module with 32Kbit EEPROM and a built-in 10-bit temperature sensor having a resolution of 0.25C.

The DS3231 RTC module Precise Real-Time Clock Module is a low-cost, extremely accurate I²C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input and maintains accurate timekeeping when the 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. The ds3231 Arduino is available in commercial and industrial temperature ranges and is offered in a 16-pin, 300-mil SO package.

For more details about the IC, the DS 3231 datasheet is attached.


Features:

  1. Two Time-of-Day Alarms.
  2. Digital Temp Sensor Output.
  3. Register for Aging Trim.
  4. DS 3231 RTC with 2032 Battery Holder.
  5. Highly Accurate RTC Completely Manages All Timekeeping Functions.
  6. Real-Time Clock Counts Seconds, Minutes, Hours, Date of the Month, Month, Day of the Week, and Year, with Leap-Year Compensation Valid Up to 2100.
  7. Configurable I2C device Address for AT24C32 using SMD jumpers on PCB (A0, A1, A2).
  8. Programmable Square-Wave Output Signal.
  9. Battery-Backup Input for Continuous Timekeeping.
  10. Low Power Operation Extends Battery-Backup Run Time.

  5. Parvathakannan Kumarasamy (verified owner)

    I have bought 2 units and they both came with dead batteries. Took some to figure it since it reads 3.3 volts perfectly. I strongly advice people to change the battery and avoid some headaches.

    I got the product on time. Ds3231 is simple a RTC. One can refer the datasheet to know the full potential of this module. The alarm function helps to set alarms and interrupt a microcontroller to wake up from sleep. which is essential for power saving when the power source is battery.
