The large majority of the sensors (modules) one can get these days are 5 volt based. Yet the Propeller is running at 3.3 volts,
So I am assuming that all the I/O pins are also 3.3 volt logic based. I didn't see anything stating otherwise, hopefully I missed
So now if we are going to use these I/O devices and sensors it implies that we will need to do a lot of level shifting.
I am not looking forward to the extra H/W on my circuits to do this for all those I/O pins. How is Parallax addressing
this to help the user community?
