Today I checked some more panels, P2.5 64*64 that I have here for a new project and a sample P3 that a supplier sent me.
I see there are some more driver chips, but all these work well with Smartmatrix. Datasheet available by Google.
P3, 64 * 32, installs ICN2028BP, the same one that install most of P2.5 64*32.
P2, 64 * 64, supplier 1, installs FM6124
P2, 64 * 64, supplier 2, install DP5220X
P2, 64 * 64, supplier 3, install ICN2028AP.
