Here is how the pins break down on the standard R1.3 schematic. I have omitted the full 180-line table for clarity, but here are the "need-to-know" groups.
Why is the revision number so important? In the world of hardware development, assuming that all boards are identical can lead to catastrophic failures. tmdscncd28379d-180ccard-pinout-r1-3
Use 10x probes with low-inductance ground springs when measuring HRPWM (150ps resolution) to avoid ringing. Here is how the pins break down on the standard R1
