“The fast Ethernet port and the three USB2 ports work nicely for me. I have this HAT packed on a Pi Zero W and use it as a gateway between the wireless and the wired worlds. The USB2 ports also recognizes my NVMe storage enclosure with its USB3 interface.
One quirk is worth mentioning so that everything does not just look black and white. The OS sometimes does not enable the fast Ethernet interface for me. However, when I make sure that the network switch is on before I turn on the Pi then everything works fine.”
