RTC DS3231 module:

Overview

The DS3231 RTC Module is a highly accurate real-time clock with a built-in temperature-compensated crystal oscillator (TCXO). Designed for precision timekeeping, it maintains accurate time even in the absence of power, thanks to its integrated battery backup. Ideal for applications in data logging, automation, IoT projects, and embedded systems, the DS3231 is a must-have for any time-sensitive electronics project.

Key Features

• High Accuracy: ±2ppm drift (±1 minute per year) due to the temperature-compensated crystal oscillator (TCXO).
• Built-in Battery Backup: Maintains timekeeping even when the main power supply is removed.
• I2C Interface: Easy communication with Arduino, Raspberry Pi, ESP32, STM32, and other microcontrollers.
• Adjustable Square Wave Output: Configurable 1Hz, 4kHz, 8kHz, or 32kHz square wave signal for synchronization.
• Built-in Temperature Sensor: Provides real-time temperature readings for added functionality.
• Low Power Consumption: Operates efficiently with minimal power requirements.

Why Choose the DS3231 RTC Module?

? Highly Accurate: More precise than standard RTC modules like the DS1307.
? Battery Backup: Retains time data even after power loss.
? Wide Compatibility: Works with a variety of microcontrollers and platforms.
? Easy Integration: Simple I2C interface with open-source libraries available.
