The schematics are available on the Wiki site.
If I can get help, I plan on making a replacement daughter / small board with extra features. Specifically a builtin 3v serial to USB adapter chip and MicroUSB port. Plus, possibly a second power switch on the right side.
There are also 2 USB2 ports off an internal hub, (that has the Keyboard & Camera as the other 2 ports). That's something I'd like available on the main board's edge.
So regarding the schematics, what do the blue circles labeled with T## indicate? I’m not familiar with this symbol, and if it indicates a test point, I could reasonably tap into these. For example, the diagram at the bottom right of sheet 19 seems to indicate a pad that can be tapped into for SDA/SDL.
