NeoTrellis 4x4

Post by Kyoshii »

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!

You tested them individually?

Some clear photos of both sides of the problem board might be helpful.

I don't see anything obvious.

Please email [email protected] with a link to this thread, your order number, and request the replacement of one NeoTrellis RGB Driver PCB for 4x4 Keypad.
