About this product
A breakout module built around the DS3231 I2C real-time clock, with an integrated temperature-compensated crystal oscillator for stable timekeeping. A CR2032 backup battery keeps the time and date running when main power is removed. Connect it via SDA and SCL to Arduino, ESP32 or Raspberry Pi for data loggers, alarms and scheduling systems.

Frequently asked questions
What is the price of DS3231 High-Precision I2C RTC Breakout Module in Egypt?
DS3231 High-Precision I2C RTC Breakout Module currently costs 115 EGP in Egypt.
Where can I buy DS3231 High-Precision I2C RTC Breakout Module in Egypt?

How do I wire the DS3231 module to an Arduino?
Connect VCC to 5 V or 3.3 V, GND to GND, SDA to the Arduino SDA pin (A4 on Uno) and SCL to SCL (A5 on Uno). Use the Wire library to communicate with the module, which uses the default I2C address 0x68.
Does the module keep time when the main power is off?
Yes, as long as a CR2032 backup battery is installed. The battery keeps the clock and date running while the main supply is disconnected, so the time does not need to be reset after each power cycle.
