Review on Waveshare Official Raspberry Controllable Brushless by Jessie Drury

This product worked as described - the thickness was just right when you had to push and pull the board when attaching and detaching it from the Pi. The heat of the Poe hat did not get excessively hot when turned on and runs continuously for a few days. Transparency I'm not 100% sure what you mean, but the POe hat sits nicely on the Pi and integrates nicely. My only problem was Po didn't work out of the box. Po has a specific purpose, and having to program it to do what it was designed to do was a little annoying.
