DS3231 RTC is Precise Real-Time Clock Module with 32Kbit EEPROM and a built-in 10-bit temperature sensor having a resolution of 0.25C.
The DS3231 RTC module Precise Real-Time Clock Module is a low-cost, extremely accurate I²C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input and maintains accurate timekeeping when main power to the device is interrupted.
The integration of the crystal resonator enhances the long-term accuracy of the device as well as reduces the piece-part count in a manufacturing line. The ds3231 Arduino is available in commercial and industrial temperature ranges and is offered in a 16-pin, 300-mil SO package.

Good quality product at a low cost. Definitely recommend this one.
Good Product. It even has an inbuilt temperature sensor with good resolution
I have been using this from a week with my NodeMCU.
Works great and have no delays even after a long time usage.
And the best thing is Product arrived on time, even in times like these.
Worked fine 👍
Very nice product works just fine. I used this as to better option for DS1307 RTC module. It works just fine with proper coding.
