Frequently Asked Questions

Q: What is the DS3231 AT24C32 IIC module and what does it do?

A: The DS3231 AT24C32 IIC module is a precision real-time clock (RTC) module designed for use with Arduino and other microcontrollers. It uses the DS3231SN chip to keep highly accurate time (hours, minutes, seconds, day, date, month, and year) and includes AT24C32 EEPROM memory for storing small amounts of persistent data. It communicates via the I²C protocol, making it very easy to wire and code.

Q: Is the DS3231 module compatible with Arduino Uno, Nano, and Mega?

A: Yes! The DS3231 AT24C32 IIC module is fully compatible with Arduino Uno, Nano, Mega, and most other Arduino-family boards, as well as Raspberry Pi and similar platforms. Simply connect VCC, GND, SDA, and SCL, and use a standard library such as RTClib to get up and running quickly.

Q: Does the module work if the main power is turned off?

A: Yes. The DS3231 module includes a CR2032 coin cell battery backup slot (battery not included). When a battery is installed, the module continues to track time accurately even when disconnected from your main power source, so your project always has the correct time on startup.

Q: What is the difference between the yellow and blue PCB versions?

A: Both yellow and blue PCB versions offer identical electrical performance and pin compatibility. The color difference is purely cosmetic — choose whichever suits your build aesthetics or makes it easier to identify modules in multi-board setups.

Q: How many modules can I order at once?

A: You can choose from 1-piece, 5-piece, or 10-piece bundles in either yellow or blue PCB color. Bulk bundles are great for classroom projects, prototyping labs, or whenever you need multiple time-keeping nodes in a larger system.
