Can I expand the board to support more than 64 control lamps & 8 general illumination lamps?

Airfield does have experimental support for daisy chaining multiple boards together, all controlled by a single CPU. This would require custom cables, new firmware, and some clever hacking of our sequencing tool output, but if it’s something you’re interested in we would be happy to work with you to make it happen. We’d actually love to see it.
