High-Precision RTC Module | I2C Real-Time Clock with AT24C32 Memory | for Arduino & Raspberry Pi

The DS3231 Real Time Clock Module delivers exceptional timekeeping accuracy with a precision of ±2ppm from 0°C to +40°C, translating to an annual drift of less than one minute. This high-precision RTC sensor features an integrated AT24C32 EEPROM for data storage and communicates via the I2C bus, making it an essential upgrade for any project requiring reliable, autonomous time tracking. Features and Benefits - High-Precision DS3231 Temperature-Compensated Crystal Oscillator (TCXO) - Maintains exceptional accuracy (±2ppm) by automatically adjusting for temperature variations, far surpassing basic DS1307 modules. - Integrated AT24C32 32K EEPROM Memory - Provides 32,768 bytes of non-volatile storage for logging data, system parameters, or event timestamps without needing an external chip. - I2C Interface with Simple Connectivity - Uses a standard two-wire interface for easy integration with Arduino, Raspberry Pi, and other microcontrollers, simplifying your wiring. - Battery Backup for Continuous Timekeeping - Includes a CR2032 battery holder to keep the clock running and maintain SRAM data during main power loss, ensuring zero downtime. - Programmable Square-Wave and Alarm Outputs - Offers flexible interrupt or clock signals to trigger events, wake up a sleeping microcontroller, or create precise timing pulses. Applications - Data Logging and Weather Stations - Timestamp sensor readings for temperature, humidity, or pressure with pinpoint accuracy for analysis. - Automated Home and IoT Systems - Schedule lights, appliances, or irrigation systems to activate at specific times, independent of network connectivity. - Clocks and Timers for DIY Projects - Build standalone digital clocks, cooking timers, or time-controlled displays with professional-grade accuracy. - Raspberry Pi and Arduino Projects - Add reliable, battery-backed timekeeping to your Pi for network-independent tasks or to Arduino data loggers. Note Package includes the DS3231 RTC module only. A CR2032 battery is required for backup operation and is not included.
