K32A-B Beaglebone Controller Cap by Kulp Lights
The K32A-B by Kulp Lights is a cape for the BeagleBone Black designed to drive WS2811 LED pixels. It has 32 local string ports fused with LED indicators that can each drive up to 800 pixels at 40 frames per second or up to 1,500 pixels at 20 frames per second. The four RJ45 differential ports can output up to an additional 48 strings by utilizing smart receivers or up to 16 additional strings by using regular receiver boards. This version also provides a Real Time Clock, temperature sensors, an OLED (included) display, and push buttons for navigating menus on the display. Finally, it has 2 RS485 outputs for DMX, PixelNet, Renard, or LOR.
The Kulp K32A-B was designed to drive a large number of pixels for dense props like MegaTrees and matrices. The 32 local string ports provides the ability to achieve very dense props without multiple expansions.
The BeagleBone can be powered by the same power supply powering the pixels. There are jumpers on the board to select either 5V or 12V power. Alternatively, the BeagleBone can be powered by its USB connection if an on-board jumper is removed.
It also has two extra headers for additional functionality. 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.
The K32A-B also has an on-board, high quality DAC chip for providing sound.
This board requires a Beaglebone Black to operate (sold separately).
If you are interested in a full build, please take a look at the mounting plate option. It allows a full build-out of the controller being powered by up to four power supplies to allow for maximum output.
