Review on Waveshare POE HAT (C) For Raspberry Pi 4B/3B+ by James Brault

Works as intended. I didn't know it had a screen until I got it. Being able to display performance data/IP/whatever you want is a nice touch, especially if you're running a headless Pi. The fan is a bit noisy and the python script they provide to control and run the display is very simple. There's only a transient threshold that determines whether the fan is on or off, so it's ultimately a cycle of constantly turning on for 5 seconds and then turning off again. Note that there are some easy ways around this. It would only be nice if they did this instead of creating a consumer. I wouldn't recommend it if you're just starting out with Linux unless they've improved/updated the documentation. Otherwise, after some adjustments, it works fine on 4B.
