DS3231 Arduino Raspberry Pi high-precision clock module

Description

Arduino Raspberry Pi high-precision clock module DS3231

DS3231 Overview

 Note that the Arduino motherboard can also use this DS3231 Module.

 The module itself can adapt to 3.3V and 5V systems without level conversion, which is super convenient!
