Full Build Kulp Controller – 32 Output Pixel (FREE SHIPPING)

This full build comes with Kulp Controller 16 port and (4) Meanwell 350-watt 12V power supplies FREE SHIPPING in a YPS Metal Enclosure. These are ready to run, no need for additional work besides setting up in xLights and/or FPP.

• What is it?The K32A-B or Kulp Controller is a cape for the BeagleBone Black designed to drive ws2811 LED pixels. It has 32 local ports (fused with LED indicators) that can each drive 800 pixels (with power injection) at 40FPS. It also has 4 RJ45 differential ports that can output an additional 16 strings. Finally, it has 2 RS485 outputs for DMX, PixelNet, Renard, LOR.For end-user usability. It provides a Real Time Clock, temperature sensors, voltage sensors, a header for an OLED display. Four push buttons for navigating menus on the display.It also has two extra headers for additional functionality. Kulp Controller FREE SHIPPING One header provides access to the I2C bus and 8 GPIO pins for additional push buttons or other triggers a user may need. The other header provides a mounting point for an optional Si4713 based FM transmitter.

  Why did you make it?

  Animated Christmas Light displays typically use ws2811 Pixels for things like house outlines, candy canes, tree’s, etc… The K32A-B was designed to drive a large number of pixels for dense props like MegaTree’s and matrices where having a lot of local ports is useful.

  NOTE: The optional FM transmitter will NOT come with any sort of antenna attached.

  Technical details: Both the DMX and ws2811 protocols are extremely timing dependent. Generally not drivable via a general purpose Linux CPU. The FPP software uses the two semi real-time PRU’s available on the PocketBeagle to handle the protocol specific timings. Using the PRU’s also allows the main CPU to be free for other things such as network IO.
