The K16-Pro is a cape for the PocketBeagle 2 that is designed to drive ws281x LED pixels. It has 16 local ports that can each drive 800 pixels (with power injection) at 40FPS. It also has 8 RJ45 differential ports that can output an additional 32 strings via differential receivers. Finally, it has two RS485 outputs for DMX, PixelNet, Renard, LOR.
The K16-Pro has a Real Time Clock (RTC) to maintain time, a temperature sensor, input voltage sensors, an OLED display with navigation push buttons, three powered USB ports, onboard sound, socket for FM transmitter, and a Gigabit Ethernet port (wired via USB2 so roughly 300Mb/s speed).
The cape provides:
16 pixel connectors in banks for four.
8 RJ45 connections for 32 more strings via differential receivers
2 RJ45 connections for DMX/LOR
3 USB-A connectors for WIFIi adapters or other USB devices
On-board pcm5102 DAC and headphone jack for sound
