Support i2c interface #7

It appears impossible to bring B6 & B7 into use as an i2c interface without major upheaval. Perhaps two surface mount pads on the underside of the extender above B6 & B7 with SMD pins?

The alternate i2c pins B8 and B9 looks possible by bringing though B8.

I wonder if there is space for one of jcw's µPlugs.
