I just got the Touch Phat hat, soldered up and whenever I attach it to the raspberry pi, it shuts off. Having the hat attached to the raspberry and then plugging it in results in no power up, just the red LED light.
It feels like something is crossed / shorting out, but I’ve been unable to detect it. Using a multimeter I checked all the adjacent solder spots and didn’t find any shorted resistance. Perhaps there’s a bette way to check for this. It feels like as soon as PIN 1 and PIN 2 gets connected the PI shuts off . (Pin 1 is the square one right? )
Any ideas on how to trouble shoot this further would be greatly appreciated.
