Since the 10" and 15" both have VESA Mount on the back, there are several options for mounting on the wall:
1. Full motion mount: Dig a hole on the wall, then fix the mount. Since it has an arm, you can pull it out, mount the frame, then push it back in.

2. Fix mount: If you can dig a bigger hole, use 2 pieces fix mount. Screw 1st piece into the wall, screw 2nd piece on Digital Signboard, then slide the Signboard onto the fix mount on wall.

3. Using no mount: Simply fix the frame onto wall using any type of screws or holder that fits the mounting holes on back of signboard, then cover the entire unit with a frame.
