Hi
I've been using the MIAC advanced and Serial modules with a 5V input.
I've now using a sensor with a 3.3v idle high output feeding into the serial modules but the modules don't appear to be able to read anything.
Is the voltage too low?
Do I need to raise the signal voltage to 5v?
Regards Dave

Re: Serial input voltages
Hi Dave,
Yes that could give you problems as the inputs have Schmitt Trigger buffers, where
input low < 1v
input high > 4v

Leigh
