Introduction
The DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal.
A real-time clock (RTC) is a computer clock (most often in the form of an integrated circuit) that keeps track of the current time.
It integrated with a battery input, which can maintain accurate timekeeping when power off. The integrated crystal resonator ensures the accuracy of clock. So this RTC solution should be worth to try.
Note: this module should be used together with EASY plug control board.

Connect It Up
Connect the EASY Plug DS3231 Clock module to control board using an RJ11 cable. Then connect the control board to your PC with a USB cable.
Upload the Code
Below is an example code. Open or drag below code to Mixly Blocks and upload.
What You Should See
Done uploading the code, open the serial monitor and set the baud rate to 9600, you should be able to see the date and the time.
