The video link did not come through for some reason.

The console output listing all looks fine. The final error output is indicating a connection issue. The lack of address in the i2c scan also indicates this.

Please try again to post the photos. Please layout all 4 of the displays next to each other, solder side up, and post a photo.

The system would only allow me to up load three images. Adding a post for the others.

I really don't believe my soldering can be bad for all 5 of the backpacks. Do you have one soldered to your standard that you could send for testing?

The single photo with all four is adequate. Don't need a separate photo of each.

Sorry for confusing term - meant the header pin solder side. So opposite side as what's shown. Need to see the soldering here:

Thanks. Those look fine.

You've wired each of those up same as in your first photo?

and run the I2C scan and get nothing with any of them?
