From Makers Electronics's description

DS3231 RTC Breakout – Real Time Clock (RTC) Breakout Module The DS3231 RTC Module is a high-accuracy real-time clock module designed to maintain the current time and date for embedded systems, microcontrollers, and digital electronics projects. It uses the RTC IC and communicates with the host controller through the I²C interface, requiring only two communication lines, SDA and SCL. The module can track seconds, minutes, hours, day, date, month, and year, including automatic adjustment for leap years. A backup coin-cell battery allows the module to continue maintaining time when the main power supply is disconnected. It’s also includes temperature-compensated timing circuitry for improved accuracy compared with basic RTC modules, making it useful for clocks, data loggers, timers, scheduling systems, automation projects, and devices that need reliable timekeeping. Features : Real-time clock tracks seconds, minutes, hours, day, date, month, and year Leap-year compensation valid up to 2100 Accuracy: ±2ppm (0°C to +40°C), ±3.5ppm (-40°C to +85°C) Battery backup for uninterrupted timekeeping I2C interface Two programmable time-of-day alarms Programmable square-wave output Low power consumption Operating voltage: 2.3V to 5.5V Specifications : Parameter Specification RTC IC DS3231 Interface I²C Communication Lines SDA, SCL Time Format 12-hour / 24-hour Timekeeping Seconds, Minutes, Hours, Day, Date, Month, Year Backup Battery Coin-cell battery Calendar Automatic leap-year compensation Accuracy High-accuracy temperature-compensated RTC Operating Temperature -40°C to +85°C Module Type RTC Real-Time Clock Module Pinout : Applications: Arduino clock projects.

From Micro Ohm's description

DS3231 RTC Module Precise Real Time Clock I2C AT24C32 (Battery Not Included ) DS3231 RTC is a Precise Real-Time Clock Module with 32Kbit EEPROM and a built-in 10-bit temperature sensor having a resolution of 0.25C. The DS3231 RTC module Precise Real-Time Clock Module is a low-cost, extremely accurate I²C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input and maintains accurate timekeeping when the main power to the device is interrupted. The integration of the crystal resonator enhances the long-term accuracy of the device as well as reduces the piece-part count in a manufacturing line. The ds3231 Arduino is available in commercial and industrial temperature ranges and is offered in a 16-pin, 300-mil SO package. For more details about the IC, the DS 3231 datasheet is attached. Features: Two Time-of-Day Alarms. Digital Temp Sensor Output. Register for Aging Trim. DS 3231 RTC with 2032 Battery Holder. Highly Accurate RTC Completely Manages All Timekeeping Functions. Real-Time Clock Counts Seconds, Minutes, Hours, Date of the Month, Month, Day of the Week, and Year, with Leap-Year Compensation Valid Up to 2100. Configurable I2C device Address for AT24C32 using SMD jumpers on PCB (A0, A1, A2). Programmable Square-Wave Output Signal. Battery-Backup Input for Continuous Timekeeping. Low Power Operation Extends Battery-Backup Run Time.
