The DS3231 Module is an extraordinarily precise I2C real-time clock module that may be used on a breadboard. This real-time clock module includes a DS3231 RTC and 32Kbit AT24C32 EEPROM, as well as a 10-bit temperature sensor with a 0.25c precision. This I2C real-time clock features an integrated temperature-compensated crystal oscillator and crystal for a low-cost, high-accuracy solution. Furthermore, the module’s built-in comparator monitors VCC status to identify power outages and instantly switch to a backup power supply. The AT24C32 has a serial EEPROM with 32,768 bits arranged into 4096 words of 8 bits each. This gives your projects 32Kb of non-volatile memory.
When the device’s main power is interrupted, the module always preserves correct timekeeping. In a nutshell, RTC modules are timekeeping systems with built-in batteries that keep the module operational in the absence of external power. As a result, we have precise module timekeeping anytime it is required. The DS3231 guarantees that the battery switch circuitry is activated automatically in the event of a power breakdown. And it’s simple to connect to Arduino, Raspberry Pi, and other microcontrollers. RTCs can be found in a variety of places, including embedded devices and computer motherboards.
The DS3231 RTC module is a low-power clock that provides certified data for seconds, minutes, hours, days, dates, months, and years. It automatically changes the end date of each month, particularly for months with fewer than 31 days, and provides genuine leap year compensation until the year 2100. The clock also has an AM/PM indication and can be set to either 24-hour or 12-hour format. There are also two configurable time-of-day alarms included.
