Description:

“Keep perfect time in all your projects — even when power goes off!”

The DS3231 RTC (Real Time Clock) Module is a high-precision timekeeping device that maintains accurate date and time information over long periods. Designed with a built-in temperature-compensated crystal oscillator (TCXO) and I2C interface, it ensures reliable performance across various microcontroller projects, from Arduino to Raspberry Pi.

This version does not include a battery, making it ideal for developers who prefer using their own CR2032 backup or power management setups. Whether you’re building a data logger, alarm system, clock, or IoT project, the DS3231 delivers superior accuracy with minimal coding effort.

🕒 Add precision and reliability to your electronics — start building smarter, time-aware projects with the DS3231 RTC Module today!
