P10 RGB Matrix Kit Unboxing

Leave a reply

I got a P10 LED Matrix Panel Kit to make a “Tune To” sign for the display. This video starts as an unboxing video and then…

I bought this P10 panel kit from DIY LED Express. It came with:

  • 4x16x32 panels
  • 1x BeagleBone Black
  • 1x 16GB micro SD car & adapter
  • 1x octoscroller
  • 1x 5V power supply
  • 4x ribbon cables
  • 4x mounting brackets
  • 2x panel power pigtails
  • 1x power wire
  • assorted hardware

I ran into trouble while making the video so I had to cut this one short so I could do some research on the issue. I got everything working in a 2×2 configuration with the panel oriented horizontally, but was having trouble when I turned the panels vertically. I’ll do more research and report back next week.

Injecting Power For RGB Pixels

Leave a reply

You will probably need to inject power at some point. It’s a simple technique, but not always easy to accomplish. This video shows how to inject power and when you will need to do it.

If you need to use more than one power supply, connect the negatives together and break the positive. This is the safest way to do it. I have heard that a load (x number of pixels) between the two supplies is enough to keep them from burning each other out, but since I have no knowledge of your electronics knowledge and for legal reasons, I’m saying break the positives.


IT IS NEVER ACCEPTABLE TO CONNECT 2 POWER SUPPLIES THIS WAY.
