The numbers on the Willow Board refer to the BCM (Broadcomm) numbers in the table below.<br /> <br /> [[File:Willow Layout.jpg|400px]]<br /> <br /> Note that 2 of the signals are not broken out to the screw connectors on the Willow board, and so you will need to solder thin wires to extended GPIO pins 27 and 28. Using thin wires it is possible to do this and still mount the display directly above the board.<br /> <br /> [[File:Willow Wires.jpg|200px]]</div>
