I would like to ask something about RS485 minimum node spacing which is described in (Page 5)
I would like to create device which consists from 3 existing RS485 devices. My plan was that I put these 3 devices together on single 2 layer PCB and connect them via single RS485 line (A, B). According to material above this shouldn´t be a good idea because there will be very small length traces between these devices.
Do you have any experience with this approach of placing more RS485 devices on same board? Is there any technique which could help the signal integrity?
