Trying to get GPIO output working

[paulknowler]

I have bought this unit https://uk.robotshop.com/products/waveshare-3-ch-relay-expansion-board-jetson-nano-w-optocoupler-isolation?gad_source=1&gclid=CjwKCAiAnpy9BhAkEiwA-P8N4kFKc7KmWEztGIl1EsF58SNJwnIir0H38mhonsYUP3kvS6DZdliXjBoCu2gQAvD_BwE and am trying to get it running. Whatever I do I cannot get the GPIO pins to act as outputs. I must be missing something fundamental but have been through everything on Jetson.GPIO GitHub page with no success. Any pointers?

Hi paulknowler,

It seems you want to use a 3rd-party expansion board from Waveshare.

Are you using Orin Nano or Jetson Nano?
The expansion board seems compatible with Jetson Nano but your topic is in Orin Nano.

Please also contact Waveshare for the usage of that board since it is not developed from us.
