The RTC DS3231 module is a real-time clock that provides accurate time delay with minimal effort. It uses a DS3231 IC, which is an extremely accurate RTC chip with a built-in 32kHz crystal oscillator. The chip also has a basic temperature sensor and alarm function. The RTC module uses a standard I²C interface and can be easily connected to various development cards (such as an Arduino® compatible board). This text is machine translated.
