The second board in my spring-time lineup is a 32-channel LED driver.
Two 5940's daisy chained. This board works with the ZB1, NB1 and NB1A.
The outputs go to two header connectors. The pinout is compatible with
the keyed IDE cables used in a lot of PCs.

The demo at http://wiblocks.luciani.org/NB1/NB1A-LED-index.html
is the Knight-Rider demo that comes with the 5940 library. I just
changed NUM_TLCS to 2. The board will be priced at $20.
I should have the schematic and datasheet later this
week.

It is easy to get increased current out of each channel using parallel
boards on a single ribbon cable.
