Casio Cable Circuit Layout

A small board is required to mount the components onto, and the diagram above shows the places where to cut the tracks. For cutting the copper tracks, you could use a drill, or a special track cutter. Remember that when you flip the board over, the cuts will be mirror reversed.

Component Side - Build

In this diagram, you can see the component side. I have also included an overlay of the tracks to visualise what is happening underneath. Boards such as these are readily available at electronics shops; hence, it pays to look around online for a bargain.

Edge Connections

In this diagram, you can see the edge connections for wiring the board. Traditionally, these points should have pins soldered to them; however, you can solder wires directly to the board if you do not have any pins

The left-hand side terminals connect to the serial DB9 connector, whilst the right hand side connects to the 2.5 mm jack plug.
