Review: Accurate and reliable - I use these for various Arduino boards and they are easy to set up and are reliable. Only downside is that you really should use the rechargeable batteries which are more expensive and harder to find. Apparently, the on-board charging circuit can cause problems with non-rechargeable batteries. other than that, these work very well.
Review: Handy - You set the clock once after installing a battery. Then you always have the proper date and time for your Arduino projects, even when they are not powered for a while. Great for time stamping pictures.

### ⭐⭐⭐⭐⭐ Decent quality PCBs. The RTC just works
*by B***S on May 30, 2025*

There are Arduino (thus Particle) libraries for these RTCs. The code is straight forward and anything you need to know about the time, date, DoW, etc. is there. It's a powerful little RTC chip.
