Sorry in advance for asking such a basic question but I just want to be absolutely sure that i'm reading this correctly.

I want to be able to read a 0-5v signal from a device connected to the MAX32 board. Are the Analog inputs on the MAX32 capable of reading a signal that is directly connected to the board that outputs 0-5v?

The next question then becomes the MX7cK board capabilities. Header 'JA' has zener's to the Analogs. But there is only 3 or 4 marked as inputs. I would also like to attach a 0-5v signal to this board but it doesn't seem to be able to accept this. Am I wrong on this one?

Everything seems to reference the Arduino examples but the more I read the more I feel that I should ask you guys. The goal is to do an AnalogRead() on the input to measure the input voltage.

The pic32 chip is a 3.3v part. All inputs can only read up to 3.3v. Pass your signal through a resistor divider network.
