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.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this DS3231 RTC module compatible with Arduino and Raspberry Pi?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003ch4\u003eQ: What can the AT24C32 EEPROM memory be used for?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is the difference between the DS3231 module with battery and without battery?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The DS3231 module with battery includes a CR2032 coin cell backup battery.
