Some days ago, we discussed about the architecture of our PCB. I will be short, and just give you the overall design.
This PCB will be used as well for the emitters and the card which will emit the master clock (but we can also use the course’s card for this).
It is designed to be relatively generic : some part will be not soldered so we can add them after if we need them. The example would be the audio codec. We don’t think we’ll need him but it can serve as two purposes : once could be measuring the speed of sound (which vary with the humidity for instance), and the second could be using one of the cards as a receiver.
