    Robust analogue-digital interface for my RaspBerry Pi. It's a shame that the device is not also available in 16 bit at similar prices.

    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.
