Vede has to be connected to ground, of course -.-

Added logos

Account for the fewer LEDs

Removed the orientation indicator since the silkscreen would be placed on the
pads of JP4.

Move R16 to a better place

Added bigger logos, board name and version

Added mounting holes (again??), logos and github URL.

* Change refs of components to all match Px
* Add solder jumpers to avoid populating the DIP switch.
* General board track optimization.

Four LEDs should be enough for the incoming signals. This has the
advantage of using a 4015 less.
