+It's single-sided to make for easy manufacture. You will see
+thet there are a few tracks on the back of the board - they all
+run between vias, and so are intended to be replaced with wire
+jumpers.
+
+The board routes the Sanguinololu 5V signal to the MBED's VIN
+so the MBED USB is not needed to power it.
+
+There is a micro-SD holder as well.
+
+The MBED pinouts are:
