Here is an updated block diagram reflecting the new layout. Most importantly, it shows the new dimensions for most of our printed circuit boards. At this point, I am fairly confident that we will have enough real-estate for the ADC and DAC boards, which was cause for concern with the previous design. Also, I have left 25 mm of clearance on the back of the chassis for the PCB on which all backplate connectors will be mounted, separately from the ADC and DAC boards. This should make it a bit easier to develop everything in parallel. It should also be noted that the backplane is much smaller now. It will sit right underneath the two touchscreen displays and will host our 4 Parallella modules and our 8 rotary encoders. It might even share some mounting hardware with the displays in order to save some space.
