Q206 PCF8563 PCF8563T 8563 Module Clock Module RTC Module DIY Clock Kit - 5 Pcs

I bought these to perform some tests on the actual device as I was considering adding the chip to one of my electronic designs, so I wanted to check how well it worked and how easy it was to use.The chip worked exactly as expected, I was surprised to find that the batteries were also included!Although my final goal was not to use these (I ended up buying the chips), they would be ideal for others working on maker projects on platforms like Arduino to add RTC support to their projects.Good device. Cheap as well.
