Real Time Clock RTC PCF85063A Breakout

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 battery holder (battery not included) and even if power is lost, real-time tracking won't be affected.
