These chips are used in the commercial Pixels. They offer 3 channels of 8bit PMW with programmable constant current source. At a street price of 20cent each they are also damn good value.
I am thinking of a small remote controller
30mA Constant Current
12 to 24v operation OR
Parts cost are around 3.00 in PWB but exc the 24 to 5 SMPS. I haven't decided on the PS yet. AND you will need a DMX 2 SPI Bridge with RS422 driver capability.
So any thoughts?
