M. Math, the Mini can handle two external interrupts with no problem. I am not sure what the maximum frequency is, but we have interrupts at about 200Hz on Int0, and 50Hz on Int1.

What may cause problems is noise. Noisey input is common, although if you are testing battery voltage, that might not have noise. If you can, look at the input on an oscilloscope. Good luck…

  Thanks a lot for your answer, I’ll test it with the oscilloscope.
  
  Finally, we have chosen the Maxi. Do you know if the maximum frequencies are the same ?

    Hi Math,
    
    I assume that the frequency will be limited by the ESD protection at the inputs. MINI and MAXI are the same from this point of view. It should be fast enough for your purpose.
    
    Let us know about the results!
    
    Thanks,
