    As others have pointed out, the resistor and/or diode between VCC and VBAT should be removed to prevent overcharging or damaging the battery. Otherwise it works great.

    Do not use CR2032 battery with this one, it has to be rechargerable LCR2032. You have to desolder the resistor in order to able to use it with regular CR2032. Search on the internet...

    A very stable RTC source. It kept exact time on battery for at least 24 hours. Good for those nano projects that require time, even after a power cut.

    Haven't tried it yet, but it arrived in fine condition, and looks like it is in a good quality.

    The DS3231 is an excellent RTC module. It was well packaged and received quickly (12 calendar days from order). I am happy to recommend it.
