DS3231 Real-time Clock Module 5pcs SMD SOP-16 by Marsrut

Description

Product Overview

The Marsrut DS3231 real‑time clock (RTC) module series is engineered to deliver highly accurate timekeeping across a broad range of electronic designs. Each of the five modules in the pack is built on a surface‑mount device (SMD) package with a SOP‑16 footprint, allowing designers to conserve valuable board space while maintaining robust electrical performance. The core DS3231 chip integrates a temperature‑compensated crystal oscillator (TCXO) that automatically adjusts for temperature variations, ensuring stability within ±2 ppm from –40 °C to +85 °C. This precision translates to reliable second‑by‑second tracking of seconds, minutes, hours, day of week, date, month, and year, with built‑in leap‑year compensation. The modules operate on a 3.3 V to 5 V supply range, making them compatible with a wide variety of microcontroller platforms, including Arduino, Raspberry Pi, ESP32, and STM32 families. Electrical specifications include a low‑power consumption of 1.5 µA in battery‑backed mode, a 32 kHz crystal oscillator, and a programmable square‑wave output that can be configured for frequencies ranging from 1 Hz to 1 kHz. The package includes five identical units, each pre‑tested for functionality, ensuring that developers receive a consistent and dependable component for their time‑sensitive projects.

Usage

These DS3231 modules are ideally suited for applications where accurate time stamping is critical. In industrial automation, the modules can be integrated into programmable logic controllers (PLCs) to provide reliable scheduling for process control, batch tracking, and equipment maintenance logs. Data‑logging devices benefit from the RTC’s ability to timestamp sensor readings, enabling precise chronological analysis of environmental, temperature, or vibration data over extended periods. Consumer electronics such as digital clocks, alarm systems, and wearable devices rely on the module’s stability to maintain correct time without frequent recalibration. Additionally, GPS‑enabled navigation units use the RTC to retain time information during signal loss, ensuring seamless handover when satellite connectivity is restored. The compact SOP‑16 design simplifies board layout in space‑constrained devices, while the SMD format allows for automated assembly using standard pick‑and‑place equipment, reducing production costs and improving repeatability. The modules are also compatible with battery backup solutions, allowing them to continue keeping time during power outages, which is essential for applications that require uninterrupted operation.

FAQ

What voltage range does the DS3231 module support?

The module operates reliably from 3.3 V up to 5 V, making it compatible with most microcontroller boards and allowing flexibility in power‑supply design.

Can the module retain time when power is lost?

Yes, the DS3231 includes a backup battery input. When a coin cell battery is connected, the module continues to keep accurate time even if the main power source is disconnected.

Is the module compatible with Arduino and Raspberry Pi platforms?

Absolutely. The module uses the I²C communication protocol, which is natively supported by both Arduino and Raspberry Pi, and example libraries are available for quick integration.

How does the temperature compensation improve accuracy?

The built‑in TCXO automatically adjusts the crystal frequency based on temperature changes, reducing drift and maintaining precise timekeeping without external calibration.

What is the recommended soldering method for the SOP‑16 package?

Standard reflow soldering with a temperature profile of 220 °C for 30–45 seconds works well. For hand soldering, a fine‑tip iron set to 350 °C and a small amount of flux will provide a clean joint.
