Pixel Extender Construction Manual

Pixel Extender Parts

To build the Pixel Extender, you need 2 things:

1. The PCB
2. The parts to solder on the board, also known as a BOM (Bill Of Materials).

The BOM parts needed to build the board are:

Mouser BOM
Part ID	Mouser PN	Description	Qty
R1	#	Resistor	3

You can buy the parts directly from Mouser: Click here for Mouser Direct Project BOM or The BOM is also available at a discount in a kit that includes the PCB from DIYLEDExpress.com

Building the Pixel Extender

Take your time and ensure you install the components in the correct orientation when required. Start by sorting the components by type and values. Look over the PCB before starting noting the location of the various components. Follow the standard procedure of installing the lowest profile parts first and ending up with the tallest.

Install shunt instead of 5V Regulator to use with 5V Pixels.

TroubleShooting

So - you've built your new Pixel Extender, connected it up to your E1.31 Bridge and tried a quick sequence and nothing happens! There are several checks to perform in order:

Visual Inspection

The very first step involves a close visual inspection of the board. Double check that you have the correct component in the correct location and in the correct orientation. Look at every single solder connection and if some are not shiny or look suspect - reflow them to be sure.

Power

Measure the voltage supplied to the Pixel Extender and ensure it's either +5vdc or +7-24vdc and ensure the power jumper is set correctly. Measure the voltage with the supply plugged in and connected to the Pixel Extender to ensure it's not shorting out. If the voltage is correct then you know the input level is correct.

Remove any/all socketed chips from the board before proceeding.
