Title: 9-30V input for Olimexino 328
Post by: josuecabrera on September 03, 2014, 09:01:43 AM
I'm new with olimexino, i read it supports inputs up to 30v. That means that i can make analogreads up to 30v? I know the power can go up to 30v but i need to read  high levels of voltage and I want to be sure it can be done before I do it.

Thanks in advance.

Only (repeat: only) the power input of the specific boards can go so high.

Signals have much lower limits, around 3V (or 5V on such boards).  You need precision dividers, voltage shifters or whatever works.
