Programmable square-wave output signal. RST output/pushbutton reset debounce input. Battery-backup input for continuous timekeeping. Simple serial interface connects to most microcontrollers. 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 The DS3231 is a low-cost, extremely accurate, I2C real time clock (RTC). The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator. 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.) Wiring instructions (for example compatible with Arduino uno r3 ) SCL → A5 SDA → A4 VCC → 5V GND → GND Package Included 3 X DS3231 Clock module Module Parameters 1. Size: 38mm (L) * 22mm (W) * 14mm (H) 2. Weight: 8g 3. Operating voltage: 3.3-5.5V 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. Clock Accuracy: 0-40 ℃ range, the accuracy 2ppm, the error was about 1 minute 6. Memory chips: AT24C32 (storage capacity 32K) 7. Real time clock generator seconds, minutes, hours, day, date, month and year. And provide valid until the year 2100 leap year compensation 8. Chip temperature sensor comes with an accuracy of ± 3 ℃ 9. IIC bus interface, the maximum transmission speed of 400KHz (working voltage of 5V) 10. Can be cascaded with other IIC device, 24C32 addresses can be shorted A0/A1/A2 modify default address is 0x57 Review: So far, it works great. - I got this module because I was getting constant errors about my time not being synchronized. I tried everything I could from setting NTP to installing various distros such as Ubuntu, Ubuntu Server, RaspiOS and Dietpi but nothing worked until I got this module. So, look no further and grab this if you need to have your time in sync. As a side note, if you are using a Raspberry Pi, please connect the module like this: VCC --> 5V SDA --> Pin3 SCL --> Pin5 GND --> Pin6 Also, you need to use a rechargeable battery such as the LIR2032. I hope this helps. Review: All different crystals - After purchasing I realized that there was accuracy differences from crystal to crystal and each of these is a different one. I'm not going for perfection, but would have been nice to know this before purchase. They do work as described and require a non-rechargable battery to function (some also need a rechargable one) so keep this in mind when purchasing. Overall good value for money and they are compatible and connect with arduino and esp32 units as needed through I2C ## Features - Clock chip: high-precision clock chip DS3231SN; The DS3231 is an RTC IC developed by Maxim Integrated. It is a low cost, extremely accurate RTC IC with communication over I2C Interface. An interesting feature of DS3231 RTC IC is that it has integrated crystal oscillator and temperature sensor and hence you don’t have to connect an external crystal. - It is a low-cost, extremely accurate I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. - AITRIP 3PCS DS3231 Real Time Clock Module RTC Sensor High Precision AT24C32 IIC Timer Alarm Clock for Arduino Raspberry Pi. Note: （Batteries are not included in the package. Please purchase the battery as shown in the picture locally） - The DS3231 is an RTC IC developed by Maxim Integrated. It is a low cost, extremely accurate RTC IC with communication over I2C Interface. An interesting feature of DS3231 RTC IC is that it has integrated crystal oscillator and temperature sensor and hence you don’t have to connect an external crystal. - A precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power failures, provide a reset output. In addition, RST pin is monitored as generating a μP reset. - The DS3231 is available in commercial and industrial temperature ranges, using a 16-pin 300mil SO package. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09KPC8JZQ | | Best Sellers Rank | #265 in Single Board Computers (Computers & Accessories) | | Brand | AITRIP | | Built-In Media | others | | Compatible Devices | Arduino, Raspberry Pi | | Connectivity Technology | I2C | | Customer Reviews | 3.8 out of 5 stars 175 Reviews | | Included Components | others | | Item Dimensions L x W x H | 1.5"L x 0.87"W x 0.55"H | | Manufacturer | AITRIP | | Memory Storage Capacity | 32768 Bytes | | Model Name | DS3231 Real Time Clock Module | | Operating System | Linux | | Processor Count | 3 | | UPC | 701715499973 | | Warranty Description | 1 | ## Product Details - **Brand:** AITRIP - **Model Name:** DS3231 Real Time Clock Module - **Memory Storage Capacity:** 32768 Bytes - **Connectivity Technology:** I2C - **Included Components:** others ## Images ![AITRIP 3PCS DS3231 Real Time Clock Module RTC Sensor High Precision AT24C32 IIC Timer Alarm Clock for Arduino Raspberry Pi - Image 1](https://m.media-amazon.com/images/I/81ZuW733JRL.jpg) ![AITRIP 3PCS DS3231 Real Time Clock Module RTC Sensor High Precision AT24C32 IIC Timer Alarm Clock for Arduino Raspberry Pi - Image 2](https://m.media-amazon.com/images/I/61+pBRD0mrL.jpg) ![AITRIP 3PCS DS3231 Real Time Clock Module RTC Sensor High Precision AT24C32 IIC Timer Alarm Clock for Arduino Raspberry Pi - Image 3](https://m.media-amazon.com/images/I/71KMlzgwoML.jpg) ![AITRIP 3PCS DS3231 Real Time Clock Module RTC Sensor High Precision AT24C32 IIC Timer Alarm Clock for Arduino Raspberry Pi - Image 4](https://m.media-amazon.com/images/I/51seNv8G68L.jpg) ![AITRIP 3PCS DS3231 Real Time Clock Module RTC Sensor High Precision AT24C32 IIC Timer Alarm Clock for Arduino Raspberry Pi - Image 5](https://m.media-amazon.com/images/I/61ddsfr0E0L.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ So far, it works great. *by C***N on May 6, 2024* I got this module because I was getting constant errors about my time not being synchronized.
