This is a keygaurd for TouchChat60basic in the commonly purchased Bam Bin case for an iPad 8. The keyguard is set with the menu button open and the speech display / message window set to 2 lines (no icons). There is no mounting, additional micorsuction tape is used to adhere to the device.
I hope this helps makes your AAC more accessible.
