Is there a way I can get a live current measurement in parallel between sense+ or TP1 and sense- on the voltage regulator?


I originally had pull-up then I edited it to pull down. I think it is pull up anyway, one device = bus driver. The rest of the devices = bus passengers or "slaves" even if it's one. The resistors keep the slaves clock and data line in time with the master. I think it's referred to as a wired logic connection. I'd guess it would work with the resistors on the board just between two the way you said. Why would you go through the trouble for just 2 boards though?
