Hi folks!
So I got my hands on 8 of the NeoTrellis 4x4, and unfortunately one shows no signs of life. Using the demo code from the learn guide, 7 of the 8 panels are detected, light up, respond to presses, but the 8th isn't detected as an I2C device at all. Aside from the NeoTrellis PCB itself, nothing changed; same elastomer pad, STEMMA to STEMMA QT cable, and my MacroPad running the demo code for a single NeoTrellis.
Is there any troubleshooting I can perform? I don't see any bad solder joints or damage, nothing lights up or anything when I try powering it on.
Thanks y'all!

Re: NeoTrellis 4x4
You tested them individually?
Some clear photos of both sides of the problem board might be helpful.

Re: NeoTrellis 4x4
I don't see anything obvious.
