Real-time clock module 5050 is a module with integrated real-time clock function. It adopts 5050 package, with small size and pin layout for easy soldering. The module usually contains a crystal oscillator, RTC chip and related circuits and components. The main function of the real-time clock module is to provide accurate time and date information. It usually has an internal counter that can continuously track time, including year, month, day, hour, minute and second. Powered by an external battery, the module can maintain the accuracy of time even when the main power is off.
Real-time clock module 5050 usually has the following features and functions: 1. Accuracy 2. Low power consumption 3. External battery backup 4. Clock calibration
