DS3231 RTC Precise Real-Time Clock I2C Module AT24C32 with Battery

The DS3231 RTC Module is a high-precision real-time clock that provides accurate timekeeping with minimal drift. It features an integrated temperature-compensated crystal oscillator (TCXO), making it more reliable than standard RTC modules. The module uses I2C communication for easy interfacing with microcontrollers like Arduino, Raspberry Pi, and ESP8266. Additionally, it includes an AT24C32 EEPROM, allowing extra data storage. This module is ideal for applications requiring precise timekeeping, such as data logging, alarms, and scheduling. This module is also available without Battery

Features of DS3231 RTC Module:

1. High-precision DS3231 RTC with built-in TCXO for accurate timekeeping.
2. I2C interface for simple communication with microcontrollers.
3. AT24C32 EEPROM for additional 32Kbit (4KB) non-volatile data storage.
4. Battery backup support for maintaining time even during power loss.
5. Temperature sensor with ±3°C accuracy.
6. Stores seconds, minutes, hours, day, date, month, and year with leap-year compensation.
7. Low power consumption, ideal for battery-powered applications.
