The K40D-PB by Kulp Lights is a cape for the PocketBeagle designed to drive WS2811 LED pixels via external receiver boards. It has ten RJ45 differential ports that can output 40 strings of pixel data. Two of the RJ45 ports can optionally be configured to output four universes of DMX instead of WS2811 pixel data.
The K40D-PB also provides a Real Time Clock, temperature sensors, a header for an OLED display (included), and two push buttons for navigating menus on the display.
The K40D-PB must be powered by an external 5V power supply through the screw terminals on the board.
