Removed from the library and updated the Eagle files.

The µZ is a left-over and has been on the silkscreen for a long time without any problems (as it is outside the border), but I can see how it will cause problems here so I will remove it from the Eagle files.

This should avoid the sample point setting:

It seems that the sample point was moved in recent versions so now the samples average the four channels into one gray value.

and new photo of old power board for archives :)

The main focus will be on I2C, SPI and GPIO signals, where the latter ones should have predictable delays because they might control timing sensitive signals (exposure control, trigger, etc). There is no need to handle large bandwidth or complex communication like AMBA here.
