I apologize if this has been asked before, but apparently the ‘search’ function is being upgraded right now, and we need some info as soon as possible.
According to NXP documentation, and the e-book, the analog inputs on the Panda are limited to 0 - 3.3V. The FEZ component shield (as well as many other component/sensor shields wire the analog connections with +5V supply. So, when I connect a 3-pin component (say for example, the potentiometer), the input voltage presented to the analog input will be 0 to +5V.
Am I not understanding something? Are we expected to convert the signals of the components from 0-5V to 0-3.3V ourselves? If so, wouldn’t it be easier to allow the component shield the ability to select either 3.3V or 5V for the analog inputs?
