Description:
The DS3231 Real Time Clock (RTC) Module is a highly accurate and versatile module designed to keep track of time in a wide range of applications. Powered by the DS3231 chip, this module offers superior accuracy thanks to its integrated temperature-compensated crystal oscillator (TCXO). This ensures that the timekeeping remains accurate, with minimal drift, even in varying temperature conditions.
The module operates on a 3.3V to 5.5V power supply and communicates with your microcontroller via an I2C interface, making it easy to integrate into a wide variety of projects. Whether you're building a clock, a data logger, or a time-stamped data system, this RTC module provides reliable timekeeping.
A key feature of the DS3231 module is its battery backup capability. By adding a CR2032 battery (not included), the module can keep track of time even when the main power supply is disconnected, making it ideal for systems where power reliability is a concern.
In addition to timekeeping, the DS3231 module offers programmable alarms and a 32kHz output pin, which can be used for generating precise clock signals or triggering events based on time.
