Option 1 – Screw Mounted (not pictured).
The GF-DIO board comes with standoff screws giving you the option to screw mount your GF-DIO board where you place within your home built cockpit.
Option 2 – Double Sided Tape (pictured below)
Another simple option is to use a few strips of double mounted sticky tape. As see here in the picture, you can run three long strips between the electronic placements on the board and place anywhere you please.
