Description
The DS3231 RTC (Real-Time Clock) module is a low-cost, highly accurate device that provides time and date information to a microcontroller or microprocessor. It features a 32 kB memory and an I2C interface, which makes it easy to communicate with other devices in a system. The RTC maintains accurate time even when the power supply is turned off, as it is equipped with a backup battery. The DS3231 can be used in a variety of applications, such as time and date stamping, timed events, and time-based alarms. With its accuracy, memory size, and simple I2C interface, it is a popular choice for many electronics projects.
The DS3231 RTC module has a socket for a rechargeable lithium cell LR2032 and a simple charging circuit.
Since the current drawn from the battery is very tiny, and a standard CR2032 cell will last way over 5 years, it does not make much sense to invest in one of the very expensive, rechargeable cells. If you want to use a standard CR2032 lithium cell, you only need to interrupt the charging circuit by removing one component. Please see the picture gallery for details.
- 2-wire connection SDA/SCL
- Operating voltage 3.3V – 5.5V DC
- Multiple libraries (from different authors) are available

I have done a comparison with the web site timeanddate (a web reference for precision of time).. my rtc have drifted of 1 second in one month.. so, 1 min for more than 6 yrs is more than enough at this price.. cr2032 installed and diode removed, working all time and keep the beat when power is missing.

Great value. You get a highly accurate real time clock, assess to 32Kb (4Kx8) of EEPROM memory, I2C (2-wire communication with module), battery backup and you can also read the temperature of the DS3231 chip.
