Hey everyone, today I picked up an incomplete Grid “kit” containing the LED/button PCB, buttons, and some enclosure parts. It’s missing a controller board I think, which I’m fine to approximate using a Teensy, but the wiring seems to be different to the NeoTrellis boards (from what I could see in the thread here), so am wondering if there’s a schematic or Teensy code to go with this version, so I don’t have to do a bunch of experimenting myself :slight_smile:

Alternatively, if there’s a place that sells the controller board I’m missing, that’d be a great help as well. I did try searching for this board but there’s almost nothing printed on the board itself, apart from “2lfi94v-0” in one corner, which I assume doesn’t mean anything.

Any help would be much appreciated!

Arduinome perhaps?

Prob have a hard time finding reference materials for that.

You may have to reverse engineer a solution.

Yeah I figured as such. It does look pretty similar to the one in this post:

… right down to the enclosure pieces looking the same. I figured it was just missing the logic board and someone may have developed a solution, but yeah maybe I will have to do some experimenting. Looks like I might have to multiplex it myself as well perhaps? I’m still not sure how it’ll work.
