The Real Time Clock (RTC) Breakout provides accurate, battery-backed timekeeping with alarm and interrupt functions, making it ideal for data logging, scheduling, low-power devices, and other time-critical embedded projects.
The RTC (Real Time Clock) is a device that carefully and precisely tracks time and dates. It is extremely precise, so it is more suitable for long-term time tracking than clocks on microcontrollers. This breakout can work with an extremely low current and thanks to the alarm feature and interrupt pin, it will allow a microcontroller to enter sleep mode until its awaken by this RTC.
It has a built-in CR2032 battery holder (battery not included) and even if power is lost, real-time tracking won't be affected.
