So I've been playing with the esp8266 controller lately and today my Usb Host Mini came in that I wanted to connect. So for this I followed the following tutorial https://www.hackster.io/139994/plug-any-usb-device-on-an-esp8266-e0ca8a
The only thing is that I didn't do the following, because I wanted to see that it actually wouldn't work without damaging the Usb Host Mini.
Now I am wondering, because I didn't do that, and just went on with the wiring, did I actually kill my ESP8266 now? Whenever I remove all the wires, and just connect the ESP8266 to my computer, it just won't show up in the ports.
If I did kill it, what did I actually do here? Did I allow 5V to run through the board and did I fry it that way? If I would've actually made the cut shown above, would it have lived? (Because I think what the cut does, is it stops the 5V from going through the circuit.)
