GPIO and Bias T with AIOv2

Are these GPIO still usable with the AIOv2 board? I kind of want to attach a rotary encoder somewhere and play with using that as an input.
Looks like I somehow need to use a ribbon cable as well, right?

Additionally, anyone got the bias-t working? I got a powered LNA and with SDR pin’s hi the bias-t LED never comes on and i get worse reception so I am assuming it is just not working.

those gpios are separate and the extension board you use doesn’t affect them IIRC, but I think most of them are already in use.

You can search this forum for a thread called “the booby trapped devterm gpio” I think.

The devterm is basically the same as the uconsole and people have tried to use those GPIOs in the past without much success

Yeah found two threads. Looks like no gpio
