The Black ODORID-C4/C5 case has openings for all outputs, including the GPIO port, making it an excellent fit for projects that are connected to external hardware.
The cover of the GPIO part can be easily removed by simply cutting a few ribs.
Clip-Fit ODROID-C4 mount with optional screw locking.
If you want a more secure lock, you can use two screws. There are two screw holes on the bottom side.
