Real Time Clock RTC DS1302 Module

The Real Time Clock RTC DS1302 Module delivers reliable timekeeping for Arduino, Raspberry Pi, and other microcontroller projects, enabling accurate synchronization of date and time information. Its compact, board-level design integrates easily with a wide range of development platforms for embedded timing applications.

• 32.768 kHz crystal oscillator for continuous time base and stability during power interruptions.
• 31 bytes of battery-backed RAM for non-volatile storage of small datasets or configuration information.
• Tracks hours, minutes, seconds, day, date, month, and year with automatic leap-year compensation.
• Low power consumption in battery backup mode, specified at 300nA on the module.
• Operates with both 3.3V and 5V systems for flexible hardware integration.

Designed with a dedicated power management arrangement and an integrated crystal oscillator, the DS1302 maintains accurate timekeeping when main power is lost and supports auxiliary data retention through its onboard RAM. The module’s battery backup capability enhances reliability for time-sensitive projects that must continue operating through power outages. Its straightforward communication protocol and common voltage compatibility simplify hardware interfacing and reduce integration time compared with older or less-featured clock modules.

Suitable for data loggers, scheduling tasks, timestamping events, and other embedded systems that require sustained and precise time tracking, the DS1302 module provides a practical balance of accuracy, durability, and ease of use for a variety of real-time applications.
