Thanks for the pointers. It actually helped clear a lot up since I hadn’t realized the Photon wasn’t just for WiFi but in fact runs everything as a complete replacement for the Teensy. My laser got used and I designed my own LED matrix for strips of SK9822 LED’s. It’s got a 5MM plywood back, chipboard grid separators, vellum, black paper grid mask for sharpness, and a clear acrylic cover all sandwiched together. I then designed a PCB for a Photon, MicroSD card reader, battery, and 74HCT245 which I then milled on the trusty Shapeoko2. (laser got a little jealous)
I just powered up the new PCB and it worked first try. There was a breadboard version prior of course. So it’s not THAT amazing it worked first try. 😛
I did have to rebuild the LED matrix twice because I could have sworn I read somewhere the pixels’ data streams from upper right but it’s actually upper left. That added an extra evening to the project. I still need to make a case for it but wanted to post some pictures and video in case anyone was interested. Thanks.

Assembling the LED matrix BACKWARDS. OOPS!
Everyone loves a good sandwhich.
(Dave Jones voice) It’s like a bought one!
Took 3 tries but I got it. Remind me to try doing soldier masks later.
Next step, build case to hold it all.
