Pixelblaze no longer works after soldering another button

I added a momentary button on the two pads located underneath the button on my Pixelblzae V3 board and now it won’t work. Logged into the side and it says it’s connected but no response from the board nor my Matrix. Anyone?

Sounds like maybe a short? Can you test those connections? You can try removing it and see if it comes back.

Answer - I solved this problem. I connected a larger voltage cable by accident and threw out the board. But I have three other boards, two of which are unable to connect via Discovery.
