Here is the circuit diagram of a compact RTC module, based on the popular RTC IC DS1307, for your everyday microcontroller projects. The DS1307 serial real-time clock (RTC) is a lowpower, full ...

Developers, makers and hobbyists looking for a real time clock module complete with an Arduino library, may be interested in the Kraztech Real Time Clock Module created by developer Christopher ...

The RTC module is crucial for keeping accurate time, even when the Arduino is powered off. It maintains the time using a small battery, ensuring that the clock remains accurate.

ビズライト・テクノロジーは、Wi-Fiとリアルタイムクロック（RTC）機能を搭載したArduino互換のCPUボード「BiZduino（ビズドゥイーノ）」を12月末に ...

Because the real time clock module is so accurate, there’s no provision for setting the time. [Barzok] says that twice a year he just hooks the Arduino up and reflashes the program with a new ...

The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.
