 1. Cut the head off a USB cable & solder it to the debug pads on the back of the Pi; extend to the right (Opposite the SD card)
 2. Connect HDMI/CSI-2 module via short ribbon cable (~40 mm); fold over and glue to back of board alighting with the SD card
 3. Wire the Ethernet/SPI module onto SPI chanel 0
