I have just introduced a 32 channel LED driver that is compatible with by NB1A, NB1 and
ZB1 board. The board works with the Arduino Tlc5940 library. http://tinyurl.com/5tg39eg
* LEDs are powered by a separate adjustable
linear regulator. Power dissipation in
the '5940's can be minimized by adjusting
the anode voltage just above the LED
* Number of channels can be increased
by using multiple cards and the
* Current per channel can be increased
by paralleling cards.
* Can be used with low-cost IDE cables.
