AnalogIn on F411-RE
My current sensor gives an output of 0-5V. Is this too much voltage for the analogin pins to handle?
The data sheet says that the ADC can only handle 1.7 to 3.6V, but makes reference to the positive reference voltage. Is this the voltage I am supplying to my sensor?

The pin for ADC can be 5v tolerant (check datasheet) but the measure is still only 0-3,3V (from 0 to 1 * 3300). You probably need an external ADC or for testing you can use a voltage divider.
