Hi Martyn,

thanks for your response :).

I really like those boards and it would be a shame to have to hide two of those in the rack. My idea therefore was to showcase all four boards with two racks. And to have some sort of symmetry on the table I would like to put one rack on the left of the monitor and one to the right.

It would look something like this … Speaker | Rack with Digitizer / Motherboard | Monitor | Rack with Sensor / RGB | Speaker.

I do not mind to have some wires running between the racks. Or would it be easier to buy a 2nd motherboard?

I want to use the digitizer as a clock/countdown and the rgb matrix for sensor readout.

Thanks a lot!
