I have 2 IC's in serial communication on a pcb design I'm working on.
I think I need to have a approximately 4.7K pull down R on each track/line if I remember correctly? ie. the lines can't be left floating
I looked back at some old pcb designs on previous but can't see them, I seem to remember I had to solder a couple on.
