DS3231 RTC Breakout

From the shop's description

The DS3231 RTC Breakout Module provides high-precision real-time clock functionality for your Arduino, Raspberry Pi, and ESP32 projects . It keeps accurate time and date tracking even when power is disconnected, thanks to its built-in CR2032 backup battery . This module uses the DS3231 chip , a highly accurate I2C real-time clock with an integrated temperature-compensated crystal oscillator (TCXO) . It maintains accurate timekeeping under various temperature conditions without the need for frequent calibration. You can easily connect it using the I2C interface (SDA, SCL) and start reading time data immediately. The DS3231 RTC works perfectly for data loggers, alarms, scheduling systems, and IoT devices . In addition, it supports both 24-hour and 12-hour formats , making it versatile for different applications. Because the board includes clearly labeled pins and mounting holes , you can install and use it effortlessly. It runs on 3.3V or 5V , ensuring full compatibility with most microcontrollers.
