A lot of sensors output go from 0 to 5V. But the ADCs on Nucleo Boards have a 0-3.3V range. The solution is to use some external resistors to reduce the input of the ADC.
Is there another solution without external resistors? I think using 5V tollerant pin, then route the signal somewhere that could tone down the signa and then enter in ADC. Is it possible?
I think about OPAMP but I notice that I can only amplify the signal.
What do you think?
