Microbit breakout

This is a first attempt at a Microbit breakout connector.

I was aware that the GPIO pins on the Microbit are too narrow to fit jumper wires on one side of the board so I tried to make a row on the other side of the board - only then discovered the pins only function on the front of the board! So, half the pins are functional - doh!
The model can obviously be edited to provide jumper pin sockets for needed pins
