Sorry, yes I did mean the TM1809s from the Wiki.
Thank you all for the information. I was trying to figure out how I could use them to make an FM sign. If my math is correct, laying these strips horizontally, I could get almost twice as many LEDs vertically than horizontally.
The LEDs are about 33mm apart on the strip, but if I put two strips up next to each other, they would be about 16mm apart.
I guess I could put the strips vertically to get the higher density in a horizontal line, but I'm starting to think about just getting something like the TM1804 and just drilling holes in plexiglass or plywood and I can set my own spacing.
Thank you all for the information.
