Love the fact it has the STEMMA QT / Qwiic connectors so that you can daisy chain your i2c devices. Haven't got it working with MicoPython yet (not a fan of Circuit Python) but i'm sure i will soon solve it.

Not comparable to the DS3231, but much cheaper and absolutely sufficient if you can update your time once a week from the internet.

product seems to be what I expected and delivered on time. Haven't had a chance to fire them up yet but not expecting any problems and I am confident that if I do run into problems, Pimoroni will sort them out as they have done in the past.

A typical value for money decision. Cheap, but does not keep time as good as more expensive alternatives. I'm updating the time once a day from the internet and using the rtc to keep the time in between. For this kind of application, the breakout is just fine.
