Kulp K128D-B

Build Specifications This Kulp K128D-B, will be built in a bud box 32026 enclosure, 35 waterproof outputs for receivers, and a 5v 350-watt meanwell power supply. Board Specifications The K128D-B is a cape for the BeagleBone Black designed to drive ws2811 LED pixels via long range differential receivers. It has 32 RJ45 differential ports that can output 128 strings of pixel data. It also has a two UART based differential outputs for driving DMX, Renard, LOR, PixelNet, etc…. The 32 RJ45 ports provide the ability to drive a ws2811 pixel differential receiver boards. Each port can drive standard differential receivers or can be configured to use either v1 or v2 SmartReceivers. Using v2 protocol, 6 smart receivers can be chained off of each of the 32 outputs. All ports can be configured to output as many pixels as the ws281x spec allows, 800 for 40fps, 1600 for 20fps. HOWEVER, the single core AM3358 processor on the Beaglebone Black cannot process 102,400 pixels (128*800) at 40fps. It will
