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

The DS3231 RTC Precise Real-Time Clock I2C Module AT24C32 With Battery is a compact timekeeping module designed for integration into microcontroller and embedded projects that require reliable time and date maintenance. This module combines a DS3231 real-time clock interface and an AT24C32 EEPROM, and it is supplied with a battery to preserve timekeeping and stored data during power interruptions.Designed for straightforward I2C communication, the module exposes standard clock and data lines to simplify connection to a wide range of development boards and controllers. The included EEPROM provides non-volatile storage for user parameters, configuration data, or small logs that must survive power cycles. The onboard battery support maintains both the RTC and EEPROM contents so time and stored information remain available after a main power loss.This module is suitable for applications such as data logging, scheduled control, timestamping events, alarms, and projects where persistent timekeeping is required. Its integration of timekeeping and non-volatile memory in a single board reduces wiring complexity and conserves board space while providing a dependable solution for preserving time and small data sets across power interruptions.
