Hello, I am setting up a radio amplifier for testing and need to send discrete signals to the amplifer and back to the software. I was successful doing this before with 1 PMOD RS485, however is there an alternate method to combine 4 PMODs together in such a way as to reduce distance? The daisy chain method would not work, seeing as how these are discrete signals, and the dimensions of the board require the PMODs to be spaced closer together. Is there any way to physically attach each PMOD to one another or any alternative to using these for testing discrete signaling? I reviewed all documentation, including the docs for the PMOD RS485 here & here but could not find anything to point me in the right direction. Is it possible to do this and combine multiple PMODS w/o using the daisy chain method outlined in the reference guide?
