  • Description

The RTC DS3231 module is a real-time clock that enables accurate time-keeping with minimum fuss.

It uses a DS3231 IC, which is an extremely accurate RTC chip with a built-in 32 kHz crystal oscillator. The chip also features a basic temperature sensor and alarm clock capability.

The RTC module uses a standard I²C interface and can easily be interfaced with various developments boards (such as an Arduino® compatible board).
