The Industrial Raspberry Pi Forum

Hi, we have several customers who are interested in Revpi Compact. And we noticed that regarding the AIO, you only mentioned the input can be used for voltage or temperature measurement, but how about current? Is there any limitation for the input currency?

Hi Wang,

our AIO module is designed to do this with on-board functionality.

For Compact, Flat and MIO you can do it with a trick. Put a resistor between the analog input and GND. As for U=R*I the voatage is proportional to the current, you can calculate the current when you know the resistance.
