capablegh Posted April 23, 2018 Share Posted April 23, 2018 What is the max input voltage that the Openscope mz can tolerate on the logic analyzer pins. What about the GPIO pins? In the documentation I noted the Oscilloscope has +/-20V measurement range and +/-40V tolerated range (in some forum). But for the logic analyzer I see only a specific mention of 3.3V. I want to be sure before I connect the logic analyzer to either 5V (some Arduino's) devices or 12V devices (e.g. old DSC832 home security board). Reviewing the PIC32 datasheet, and assuming I am correctly interpreting the Openscope reference manual, I can guess that the DIO[0-9] pins are 5V tolerant. Am I correct? Also, to ensure that the scope is protected I would need to not only have a voltage divider in place, but also a zener diode to ensure the voltages remain within range... what do you suggest/recommend?
