Hello! Paul you are quite correct there. The basic styles are indeed as you've described. The standard controller can only make use of the 16x20 style. The larger ones would use either two controllers, appropriately wired, or even a custom designed controller.
Take a look at the pages in the current Jameco catalog on that subject, or failing that their website. Or even the relevant portions of the Sparkfun site. Incidentally what is the brains behind the Hobby boards configuration? Is it the DS2408 device? --- Gregg C Levine [email protected] "This signature is not the same one. Move along!
