Tablet

This is an Open Source Tablet Design that i cooked up really quickly. It Could be used to create a Tablet PC out of a Raspberry Pi 3 (which includes Bluetooth LE and WiFi). Though you'll probably need to desolder several things from the board if you want it to be thin as most modern tablets currently are. In this design you'll notice some oddities:

1. No USB Ports (mice or keyboards through bluetooth, USB sticks aren't really needed when everything is cloud based)
2. No Charging Port (Wireless Charging)
3. Slots around the 4 quadrants of the bezel (act as acoustic cavity for better sound and Lights for system notification)
4. No Front Facing Camera (for security reasons, scanning QR codes or taking pictures doesn't require this)

You will probably need to make some modifications depending on your touch screen panel (mounting holes will probably need to be adjusted) and the thickness of the tablet (depending the thickness of your SBC)
