Help! conductivity issues

Post by JTG0912 » Tue Jun 12, 2018 5:43 am

I have solder my raspberrypi to my PCB. All of my points connections are good except my right bumper button. No matter how many times i try to solder that connection I never get a reading from my multimeter.

Another issue I'm having is when I plug in my LCD and power up my pi via USB. The Retropi image loads up and I can click a to configure. The issue is my dpad is not working at all. My connections for these buttons are fine, but when I try to use the actual buttons, nothing happens. Some advice would be awesome!

Show pictures, and you have continuity for the dpad directions from GPIO to the test pads? If you have issues making continuity you can stick a resistor leg or pin from a pin header into the gpio till it hits bottom while the solder is molten then let the solder cool and cut the wire/pin flush.

Don't contact me about obtaining my board files (as you will not get them). If my Boards or PCB Kits are sold out, they will be restocked as soon as I can get them and there is demand for them. You can join the mailing list on my Website to be notified when they are available.
