10 PCS Raspberry Pi RTC DS3231 Module

Description:
A very compact real-time clock (RTC) module is based on the high accuracy DS3231 IC and includes a rechargeable battery backup. This module also has a header with a pinout specifically designed so that it can be plugged directly into the IO header of your Raspberry Pi without any need for additional wires or soldering. The module makes use of the Raspberry Pi's I2C hardware interface.
