The Keyestudio DS3231 High Precision I2C Real Time Clock Module features an integrated TCXO and crystal for exceptional timing accuracy. It includes a battery input to maintain timekeeping during power loss and an internal oscillator that ensures long-term precision while minimizing component count. Supporting both commercial and industrial temperature ranges, this module operates seamlessly at 3.3V or 5V without requiring a level shifter, making it a reliable and convenient choice for precise timekeeping in embedded systems.
