DS3231 Real Time Clock Module is a low-cost, highly accurate Real Time Clock which can maintain hours, minutes and seconds, as well as, day, month and year information. Also, it has automatic compensation for leap-years and for months with fewer than 31 days.

DS3231 Real Time Clock Module is a six terminal device, out of them two pins are not compulsory to use. So we have mainly four pins. These four pins are given out on other side of module sharing the same name.

DS3231 Real Time Clock Module is a savior. It’s perfect for projects containing data-logging, clock-building, time stamping, timers and alarms. At the heart of the module is a low-cost, extremely accurate RTC chip from Maxim – DS3231. It manages all timekeeping functions and features a simple two-wire I2C interface which can be easily interfaced with any microcontroller of your choice.

DS3231 Real Time Clock Module Pin Configuration

DS3231 Real Time Clock Module is a six terminal device, out of them two pins are not compulsory to use. So we have mainly four pins. These four pins are given out on other side of module sharing the same name.

Pin Name Description
VCC Connected to positive of power source.
GND Connected to ground.
SDA Serial Data pin (I2C interface)
SCL Serial Clock pin (I2C interface)
SQW Square Wave output pin
32K 32K oscillator output

 

Applications
  • Robotics
  • Gaming
  • Servers
  • Computer Peripherals
  • GPS
  • Utility power meters
Battery Backup

The DS3231 incorporates a battery input, and maintains accurate timekeeping when main power to the device is interrupted. The built-in power-sense circuit continuously monitors the status of VCC to detect power failures and automatically switches to the backup supply. So, you need not worry about power outages, your MCU can still keep track of time.

Onboard 24C32 EEPROM

DS3231 RTC module also comes with a 32 bytes 24C32 EEPROM chip from Atmel having unlimited read-write cycles. It can be used to save settings or really anything. The 24C32 EEPROM uses I2C interface for communication and shares the same I2C bus as DS3231.

The I2C address of the EEPROM can be changed easily with the three A0, A1 and A2 solder jumpers at the back. Each one of these is used to hardcode in the address. If a jumper is shorted with solder, that sets the address.

DS3231 RTC Module Pinout

The DS3231 RTC module has total 6 pins that interface it to the outside world. The connections are as follows:
