Step 4: Wiring the Screen Pack
1 | Measure an approximate length of HDMI cable from the LCD logic board to the bottom of the wood panel.
2 | Very carefully cut around the plastic sleeve of the HDMI cable. You should then be able to pull the sleeve off the wiring.
3 | Cut around the molding of the HDMI socket. Make sure you don't catch any of the wires. I have used a small piece of heat-shrink at the plug end to help support the loose wires.
4 | Using some spare IDE cable connect four wires to both the WiFi PCB & the Bluetooth PCB. Use the red pin 1 indicator as the +5v wire. Fit the ends with DuPont connectors.
5 | Separate the wires from an IDE cable. Strip the ends to show bare wire, tin the wires with solder and place small lengths of heat-shrink over the wires. I have put the cable into a vice (with rubber grips) to hold the cable while soldering.
6 | There are 15 wires for the HDMI, 2 for the power supply, and 8 for the two USB PCBs. They all need to be soldered onto the IDE cable. I started with the HDMI. It is worth putting some heat-shrink over the wires to help with running the wires later,
7 | Use 3 wires for the +v supply and another 3 for gnd. Make sure all connections are protected with heat-shrink.
8 | Fit DuPont connectors to the IDE cable for the USB PCBs. I have marked one line on each with red heat-shrink, this will be used to correctly orientate the plug and socket so there are no crossed wires.
9 | Connect up all the wires making sure it all plugs in OK.
