The DS3231 Real-Time Clock (RTC) Module is one of the most popular and reliable time-keeping solutions for Arduino, Raspberry Pi, and other microcontroller projects. Unlike simpler RTC chips such as the DS1307, the DS3231 features a built-in temperature-compensated crystal oscillator (TCXO), which delivers exceptional accuracy with a typical time drift of only ±2 parts per million (ppm) — equivalent to just a few seconds per year. This makes it ideal for data logging, digital clocks, timers, alarm systems, and any project requiring precise time tracking even after power loss, thanks to its integrated battery backup.
In this post, I am sharing a fully functional Proteus model of the DS3231 module that you can download for free and use in your simulations, saving you the hassle of building the component from scratch while testing your RTC-based circuits virtually before hardware implementation.

Once you have downloaded it, simply right click on the model and click on Make Device. Then click on Next, until you come to where in Proteus library you want to save the model. The following video shows how to save the Proteus model:
