adalogger 32u4 soldering damage? Moderators: adafruit_support_bill, adafruit

Hi, I've been playing around with the mini GPS pa1010d and had finally decided to wire my project more permanently.
I did have the Stemma QT breakout cable, but the end of the pins snapped, so I decided to just solder directly as per the Arduino I2C diagrams for the PA1010d

Here's the problem...
When soldering the 3.3v pin on the 32u4, I slipped and the soldering iron touched the board.

I cant see any visible damage, but I'm now only getting 0.54v from the 3.3v pin, regardless of if the board is USB or LiPo powered.

Is there any other reason why this could happen???

It's possible. Can you post a clear closeup of that area of the board?

Thanks Dave, here's the front and back of the board.

Great photos! Thanks.

It looks a little messy and I'm wondering if there is some stray solder around the pads.

Also, those aren't very good looking solder joints. See how they are round and ball-like? They should look more like circuit tents. See https://learn.adafruit.com/adafruit-guide-excellent-soldering and https://learn.adafruit.com/collins-lab-soldering.
