DS3231 AT24C32 IIC Precision Real-Time Clock (RTC) Module

Keep your electronics projects perfectly in sync with the DS3231 AT24C32 IIC Precision Real-Time Clock Module. Designed for Arduino, Raspberry Pi, and other microcontroller platforms, this compact module delivers highly accurate timekeeping thanks to its temperature-compensated crystal oscillator (TCXO). Whether you're building a data logger, automated scheduler, or any time-sensitive DIY project, this module gives you the reliability you need.

Available in two variants — with backup battery (CR2032 coin cell included) or without battery — so you can choose the configuration that best fits your build.

Key Features

  • High-Precision Timekeeping: DS3231 TCXO maintains accurate time even with temperature fluctuations
  • AT24C32 EEPROM: 32Kbit onboard memory for storing data and configuration settings
  • IIC / I²C Interface: Simple two-wire communication, compatible with Arduino, Raspberry Pi, ESP8266/ESP32, and more
  • Backup Battery Support: Keeps the clock running even when the main power is disconnected (battery variant)
  • Compact SMD Design: Small form factor fits neatly into breadboards and PCB layouts
  • Wide Voltage Range: Works with 3.3V and 5V systems
  • Condition: Brand new

Frequently Asked Questions

Q: What is the difference between the DS3231 module with battery and without battery?

A: The DS3231 module with battery includes a CR2032 coin cell backup battery. This means the real-time clock continues to keep accurate time even when your main device is powered off. The version without battery still functions as a precision RTC clock module but will lose its time setting when power is removed unless you add a battery separately.

Q: Is this DS3231 RTC module compatible with Arduino and Raspberry Pi?

A: Yes! The DS3231 AT24C32 IIC module uses the standard I²C (IIC) two-wire interface, making it fully compatible with Arduino (Uno, Nano, Mega), Raspberry Pi, ESP8266, ESP32, STM32, and virtually any other microcontroller that supports I²C communication.

Q: What can the AT24C32 EEPROM memory be used for?

A: The onboard AT24C32 provides 32Kbit of non-volatile EEPROM storage. You can use it to save configuration data, sensor readings, user settings, or any small data set that needs to persist between power cycles — making this module ideal for data logging and automation projects.
