GPIO

Can I use GPIOs on the MiiVii Evo Xavier?
If so, how does it differ from the normal Jetson xavier?

Hi

Sure, the green socket is isolated IO on EVO Xavier.
There are 8 DI and 8 DO.

The Jetson Xavier Dev Kit has only 3.3V GPIO, and it's not isolated, which is not suitable for external usage.
On EVO Xavier, the IO is isolated, and support wide range, which is robust in industry usage.
DI 3.3-50V DC
DO 5-40V DC

You can refer the following links to get the usage and device name

Thanks for telling me.
Is it possible to control this GPIO in python or other languages?

Hi， yes you can

I set the DO to high and measured the voltage, but it was still 0. It says that it is possible to go from 5V to 40V, but how should I change the output?

I set the output of the DO to high with the command [echo 1 > /sys/class/gpio/gpio/gpio232/vlaue], but when I measured the voltage, it remained 0V.
I would appreciate it if you could tell me the cause and how to solve the problem.
