Overview

The MOD-RTC is a real-time clock module based on the highly accurate DS3231 IC, featuring an integrated temperature-compensated crystal oscillator (TCXO). It is designed to provide precise timekeeping for embedded systems via a standard I2C interface and includes a battery backup capability to maintain time during power loss.

Why Choose This Part

The module utilizes the DS3231, which is significantly more accurate than standard RTCs due to its internal temperature compensation. It features Olimex's UEXT connector, allowing for simple plug-and-play integration with a wide range of development boards without soldering.

Applications

Data Logging
Providing accurate timestamps for sensor data in environmental monitoring or industrial logging applications.
Scheduled Task Triggering
Managing precise power-on/off cycles for remote systems to conserve energy based on time of day.
Clock and Calendar Displays
Serving as the time base for digital clocks, calendars, and automation controllers requiring high long-term stability.
