What is it?

The K4-PB is a cape for the PocketBeagle designed to drive ws2811 LED pixels. It has 4 local ports (fused with LED indicators) that can each drive over 800 pixels (with power injection) at 40FPS. It also has a 3pin UART header that can be used to drive a single DMX universe or for PixelNet/Renard/LOR.

The K4-PB is very small and is designed to fit into a small TA-200 enclosure. With a “nano style” USB WIFI adapter, it fits perfectly.

Why did you make it?

Animated Christmas Light displays typically use ws2811 Pixels for things like house outlines, candy canes, tree’s, etc… The K4-PB was designed to drive a large number of pixels, yet remain very small so it can be easily hidden or mounted onto the prop.

What makes it special?

The 4 local ports provides enough outputs to handle most situations where a small controller is desirable. It’s more than the 2 ports of the various Raspberry Pi controllers, but not as large as the standard 16 port controllers that are typically used for pixel dense locations.

The PocketBeagle can be powered by the same power supply powering the pixels. There are jumpers on the board to select either 5V or 12V power.

You WILL need:

  • ws2811 pixels
  • A good quality SD card with the latest FPP image installed on it. The latest FPP image can always be found at http://kulplights.com/bbb/
  • A USB network adapter – ethernet is preferred for initial setup, but WIFI (adapter must be supported by Linux/Beaglebone/Raspberry Pi) can also work if you use a micro-usb cable to connect to the PocketBeagle to do the WIFI setup.

    Great little controller especially for a first timer like myself. Easy to setup and get going, will defiantly be adding more Kulp controllers as the years go on and the show grows. Great work Daniel and thanks.

    Experienced with Dan’s controllers….they are full of pixel power and very cost effective. I bought this K4-PB because of its size and that was built to fit the TA200 box. I’ll buy more.

    Fantastic product, works great with the TA-200 enclosure to create yourself an awesome pixel controller.

    Great little controller, I have this running my permanent trim lights. Easy setup and a good quality product.

    These are Great units for my Projects, will be looking on getting more K4-PB for my Future Projects instead of the Pi with Picap as the working models have hard to find
