About this item

Product details

This listing includes 5 pieces of DS3231 AT24C32 Real Time Clock (RTC) modules, designed for use with Arduino, Raspberry Pi, STM32 and other microcontroller systems. The module features a high-precision DS3231 chip with built-in temperature-compensated crystal oscillator (TCXO), delivering far more accurate timekeeping than traditional DS1307 modules. It provides stable time and calendar tracking with minimal error, even in varying temperatures. With the standard I2C (IIC) communication interface, the module is easy to connect and integrate into your projects. The integrated AT24C32 EEPROM chip allows you to store small amounts of data for added functionality. Equipped with a CR2032 battery holder (battery is not included), the module continues to keep time when the main power supply is disconnected, ensuring your projects maintain accurate timestamps. Compact and lightweight, this RTC module is ideal for DIY electronic projects, data loggers, smart home devices, embedded systems, and any application requiring reliable real-time clock functionality.
