LED Matrix - Tri Color - Large

sku: COM-00683

Description: Triple Color LED Matrix! This large matrix has 64 Red, 64 Green, and 64 Blue individual LEDs built into one common cathode housing. It's a monster to control, but just imagine what kind of colors you could produce by mixing!

These are the new, readily available units that just arrived. Unit comes with a black finish and opaque LED lenses.

The datasheet pin numbers don't seem to match the grid. Does anyone have a proper pinout for this?

The pin-out is just fine, use your DMM in diode mode to identify pin 1. The color intensity varies noticeably between the blue LEDs. Timing constraints with a typical MCU will limit you to about 512 colors. Wish the price was more modest.

I would recommend using a PWM/constant current driver such as a TLC5490 to handle the dimming. This frees up your micro to do a lot of other stuff. You typically just need to shift in the brightness levels once per row (using SPI). It's easy to acheive 30 fps and 24 bit color this way.

You mean TLC5940. I knew of the part but could not find the datasheet on TI's website. http://focus.ti.com/lit/ds/symlink/tlc5940.pdf They have some apnotes (see bottom of page) http://focus.ti.com/docs/prod/folders/print/tlc5940.html

So, does anyone have 23001.60$USD to buy 768 of those things to make a giant Nintendo DS display (256 x 192 pixels)?

It appears, from the picture and the reports of success in using this device, that there's an error in the description. If the LED lenses were "opaque", no light could get through them. They appear to be "translucent" and "diffusive". Eric

Er, exactly what colour is "Kelly" (from the datasheet)? I can't even figure it out from the context. Maybe I'm "Kelly colourblind"? :)
