About RTC Modules
RTC Modules
RTC modules are small, stand-alone real-time clock devices that keep track of the date and time, regardless of whether the main system is powered on or off. These devices are often used in embedded systems and consumer electronics to provide a reliable time source for applications such as time stamping, scheduling tasks and alarms. An RTC module is usually powered by a built-in battery that allows it to operate autonomously even when the main system is powered off. The module can be set up and programmed to provide various timing functions, such as counting seconds, minutes, hours, days, months, or years. It can also be used to calculate the exact time when an event occurred, such as a power failure. The accuracy of the timing functions depends on the type and quality of the module used.
