Anyone know of a source for blue LED matrix modules for Stern low voltage DMDs?
I figured out they are 8X8 matrix, 20mm X 20mm 1.9mm pitch
Anyone know if they are common anode or common cathode?
I found them in red or green but nowhere in blue.
Found a manufacturer that makes compatible LED Matrix Modules in many colors. Still looking for pricing but will update when I have something.
Still need to figure out if the modules used have the anodes on the rows or columns.
I realize that I'm 2 year late, but here is the information that you requested:

for about $70, you could swap out all 32 blocks to make your low voltage DMD blue
