The DS3231 AT24C32 I2C RTC Module is a highly precise Real-Time Clock Module equipped with a 32Kbit EEPROM and an integrated 10-bit temperature sensor with a resolution of 0.25°C. This module stands out due to its low-cost yet exceptional accuracy, featuring an integrated temperature-compensated crystal oscillator (TCXO) and a crystal that enhance its timekeeping precision. The DS3231’s TCXO ensures that the clock maintains high accuracy across a wide range of temperatures, minimizing drift and the need for frequent recalibration. The module also includes a battery input, which ensures that timekeeping remains consistent even if the main power is disrupted. This makes the DS3231 ideal for applications where stable and reliable timekeeping is crucial. Available in both commercial and industrial temperature ranges, the DS3231 is housed in a 16-pin, 300-mil SO package. For detailed specifications and further technical information, refer to the DS3231 datasheet. Features of DS3231 AT24C32 I2C RTC Module : Two Time-of-Day Alarms. Digital Temp Sensor Output.
