The pinheads for the motherboard-daughterboard were reconfigured to have the ability to use the switch terminals without the need for a second set of terminals to choose from when installing switches. This required some critical thinking. The connectors had to be moved from their locations on the screen to a new location. The connectors used to be three pins but have changed to six pins to accommodate the switches and carry RAW voltage. The addition of the RAW voltage is so power can be brought in from either side of the board or split power from the board.

New motherboard-daughterboard connectors

The routing was attempted for the board layout. The program routes for a top and bottom layer but presumably the chosen board manufacturer only uses single layer boards. The shape of the circuitboard couldn't be modified so a wire was drawn around the restricted area and no wires were routed through that area. This is the area which will be used for installing the wall-mounting brackets.

Routed circuitboard
