DS3231 RTC I2C Module: Precision Real Time Clock Memory Module

The DS3231 RTC I2C Module is a highly functional breakout that incorporates DS3231 RTC and 24c32 EEPROM ICs. This module is an ideal choice for DIY projects that require accurate real-time clock information. It features an I2C communication interface and also includes a housing for a CR2032 clock battery specifically designed for the RTC module.

Key Differences

The primary distinction between the DS3231 and the DS1307 lies in the fact that the DS3231 is equipped with a temperature-compensated crystal. This feature enhances the precision of the DS3231.

Important Information

Please note that the board charges the battery using the VCC voltage. If you intend to use a non-rechargeable battery such as a CR2032, modifications to the board are necessary. Specifically, the resistor or zener diode marked in yellow must be removed if the board is to be used with a CR2032. Visual guides for this process are provided below. However, the board can be used with rechargeable watch batteries like the LIR2032 without any modifications.
