Heres a picture of the Layout of the Express at this point. I have not tried to make it small but instead stayed with the same PCB size and mounting as the Freestyle. It has optional Led's for each channel that will dim with their Channel.
As you can see it is just a 16 channel Pic dimmer with on board SSR. There is nothing really special about the hardware except the pic and the extra goodie above it, a 64K flash memory chip to allow the dimming curves, etc to be stored. The Pic is a 16 bit pic and The firmware is very different to allow it to do the new abilities. The hardpart of this setup is the Firmware but it is coming along well. Allong with the firmware I am having to create the Software that programs the unit.
