## Overview

The DS3231 Real Time Clock Module is a high-precision, temperature-compensated RTC with integrated crystal oscillator and 32K AT24C32 memory. Compatible with 3.3V and 5V systems, it features a fast I2C interface and supports calendar alarms and leap year compensation up to 2100. Sold in packs of five, it’s perfect for Arduino, Raspberry Pi, and other microcontroller projects requiring reliable, accurate timekeeping.

## Description

Description: The DS3231 is a high precision Real Time Clock Module which can maintain hours, minutes and seconds, as well as, day, month and year information. The module can work on either 3.3 or 5V. You can use a typical C-R-2032 3V b-a-t-t-ery to power this RTC module, kindly note that the b-a-t-teries is not included in this listing! Specification: Operating voltage: 3.3-5V Clock chip: high-precision clock chip DS3231 Clock Accuracy range: 0-40 ℃, the accuracy is 2ppm, the error is about 1 minute for a year With 2 Calendar alarm clocks Programmable square-wave output Real time clock generator seconds, minutes, hours, day, date, month and year timing and provide valid until the year 2100 leap year compensation The chip itself is with temperature sensor whose accuracy is around ± 3 ℃ Memory chips: AT24C32 (storage capacity 32K) IIC bus interface, the transmission speed of 400KHz @ working voltage of 5V Can be cascaded with other IIC device, 24C32 addresses can be shorted A0/A1/A2 modify default address is 0x57 Pin Description: 32KHz：32KHz output SQW：Active LOW Interrupt or Square wave output SCL：Serial Clock Input SDA：Serial Data I/O VCC：DC Power Pin GND：Ground Connection schematics ( Wiring with Arduino for example, see attached picture): SCL → A5 SDA → A4 VCC → 5V GND → GND If you use other board with this RTC module, you need check and change their SCL and SDA pins. Nano: SDA→A4, SCL→A5 MEGA: SDA→20, SCL→21 Leonardo: SDA→20, SCL→21 Note: Working with the RTC requires two important steps: 1, Setting the current time, so that the RTC knows what time it is. 2, Retaining the time, so that the RTC module always gives the correct time, even when it is turned off. Package Includes: 5 X DS3231 RTC Clock Module (Ba-ttery is NOT included)

## Features

- 1, Main chip DS3231 is a high precision RTC IC with I2C communication, it has integrated crystal oscillator and temperature sensor and hence you don't have to connect an external crystal or temp sensor
- 2, DS3231 RTC module can work on either 3.3V or 5V. You can use a typical C-R-2032 3V b-a-t-t-ery to power this RTC module
- 3, You need prepare C-R-2032 or L-I-R-2032 b-a-t-t-ery since it is not included in this listing
- 4,Clock chip: high-precision clock chip DS3231(there are 3 different chips for this clock module, DS3231N,DS3231SN and DS3231M, we send it by randomly
- 5, What you will get is: 5 X DS3231 RTC module. If you have any question or need any support, pls feel free to contact us by click "WISHIOT" under the shopping cart

## Questions & Answers

**Q: If i run it off of 3.3v, and use a lir2032 battery (which are listed as 3.6v), will it actually charge those batteries?**
A: These are real-time clocks. Not chargers.
Mine required 5vdc coming in.
