ELS Control Panel Assembly and Wiring to the Launchpad

The wiring diagram is in the project WIKI



But for replacing the 5 pin header on the display board with an angled connector on the bottom side this part of the build was easy.  Drilled a 5/8 hole for the aircraft style connector GX16-8.   Viewed from the wire end the wires go ccw around the GX16-8. in the same order as the DuPont header starting with 5V. The heat shrink make me feel better about potential short.  Maybe I should have tangled the wires a bit to prevent cross talk.  They are short so maybe OK.

The order is

5V        RED
GND    BLACK
STB     BLUE
CLK    GREEN
DIO     YELLOW

This cable exits the bud box via the round connector.  The matting end of this connector is one end of the cable that ends up at the launchpad.    For now I am going to make that a single cable using cat5.    When the launchpad is mounted in a case I will break the cable with a 2nd 

The cat5 has 4 twisted pair.   
5V            BROWN                   
GND        BROWN/STRIPE     

STB         BLUE        

EARTH   BLUE/STRIPE
CLK        GREEN

EARTH   GREEN/STRIPE

DIO         ORANGE

EARTH   ORANGE/STRIPE

The 3 EARTHs are unconnected at the display end and tied to the chassis ground on the controller side.

The cat5 end of the cable prior to heat shrinking and all buttoned up. 

Two layers of heat shrink wrap were used over the wire bundle to get enough bulk for the strain relief clamp to grip.

The short Dupont to GX16-8 male is ready to go into the bud box.  The GX16-8 female needs to have a DuPont connect on the other end.  After a continuity test the display can be connected to the LaunchPad and tested.

I think there are 3 additional cables.

1. Launchpad to Motor Controller
2. Motor Controller to Motor
3. Launchpad to encoder.

The first is run entirely inside the electronics case.  There are screw terminals on the motor controller.  It connects to screw terminals on Jame's board.  It will get ferrules on both ends.  

The second has been supplied with the motor kit.

The encoder has a long pigtail   It connects to the launchpad with Dupont connectors.   Current plans are to used a 2nd GX16-8.   Maybe color code them and block of a different pin on each so they can not be interchanged.
