Kills Pi Zero W Boards

I have a pi hat with the Waveshare logo on it. For me it was a disaster. If I power the board via USB and apply power to the DC jack (in the range of 6-9V DC) the Pi gets very hot but I can drive the servos. This is probably due to poor power supply isolation. When I try to power the Pi Zero W from the DC input jack, this board dies. Unfortunately I tried another board and killed it too. Then I was stupid enough to try again when I got a new Pi Zero (not the W model) and guess what? It's also dead. Trying to save a few bucks on Sparkfun or Adafruit devices is going to cost you. In my case about $50.
