DS3231 RTC Memory Module Precise Real Time Clock I2C AT24C32

The DS3231 RTC Memory Module is a highly accurate real-time clock module with integrated temperature-compensated crystal oscillator (TCXO) and crystal. It provides precise timekeeping functions and is designed for use with Arduino and other microcontroller projects.

  Key Features:  

• Accuracy: The DS3231 RTC module offers high accuracy, with a deviation of ±2ppm from 0°C to +40°C and ±3.5ppm from -40°C to +85°C.
• Timekeeping Functions: It can maintain seconds, minutes, hours, day, date, month, and year information, with automatic adjustment for months with fewer than 31 days, including leap years.
• Alarm Clock: The module features two configurable alarm clock settings.
• Temperature Sensor: It includes a digital temperature sensor with ±3°C accuracy and 0.25°C resolution.
• Battery Backup: The module has a battery holder for a 2032 coin cell battery, allowing it to maintain accurate timekeeping even when the main power supply is disconnected.
• I2C Interface: It communicates with the host microcontroller via the I2C interface, supporting fast (400kHz) data transfer.
• Operating Voltage Range: The module operates within a voltage range of 2.7V to 5.5V, with a separate voltage supply for the RTC at 2.2V to 5.5V.
• Configuration Options: The device allows for configuration of the I2C device address using SMD jumpers on the PCB (A0, A1, A2).
