I am a newbie to soldering, but I believe that everything should be good to go. It doesn’t seem like I have anything crossed and have soldered all of the connection. When I plug in the hat to the GPIO pins I basically lose access to my RPi4. The HDMI output of the display shows nothing. I cannot VNC into the pi or ssh to access the terminal either. When I unplug the micro dot phat and restart, everything is fine and I get display with access to vnc and ssh.
I am wondering if you have any guidance and if I need to change some settings on my pi to get access while the phat is plug in. I am also starting to think that I the phat may be screwed up on some way. I have followed the startup instructions to the best of my ability and have downloaded the associated python files/commands and enabled i2c.
