The board is easy to understand There are many instructions on the internet on how to use it. It works well. I accidentally connected a pin wrong and the AD chip got very hot until I noticed it, but it still works fine.
The resolution of the chip is 256 steps (8 bit). For my purposes a sufficient resolution but if someone has highly accurate sensors, not the right converter (with a temperature sensor that measures between -50C and 150C, a maximum of plus minus 1C temperature can be distinguished. But since simple sensors are not much more accurate anyway, it doesn't really matter.
