USB HUB2.0 CH334

Overview

There are two boards in total: one with a USB Type-C interface and the other with a USB header pinout. This board features an equal-length 90-ohm differential impedance design. With the NC (non-uniform impedance) filled in, it can operate at 105 degrees Celsius, similar to industrial applications. An additional USB male connector version includes ESD protection, while unnecessary auxiliary components for industrial applications have been removed.
The initial board speed test is shown in the following figure.

I feel it is a waste of energy. Will the M4 series program developed by the manufacturer be useful later? I wonder when the one with network port will be available? :funk:
