USB-HUB

Overview

This is a USB 2.0 hub, not supporting USB 3.0. Since it's based on the SL2.1A board, its primary function is serial port expansion, which is sufficient. There's also a cover for lighting effects, based on an STC8G1K08A LED with WS2812 LEDs. Because the SL2.1A lacks port status output, it doesn't support microcontroller detection of which port is connected. The plan is to implement this effect using an FE2.1 board and a microcontroller in the future. See the attached image
for

sample microcontroller code and BOM.
