Add Bluetooth 5.0 to the keyboard
Based on the trend of wireless technology, we try to add the function of Bluetooth 5.0 to the cyberboard. But we ran into a problem: the antenna would be obscured by the aluminum alloy case.
So we need to make a hole in the front to expose the antenna, and then we cover it with a piece of non-metal material.
