So that pad we're crossing is the MCU side of R1545, NC between GPJ9
and PMU.SHUTDOWN, correct ?

By the way, for pre-v5 boards, there's an easily accessible VB_SYS
on the "west" side of L1704, the 2u2 inductor in the middle of a
group of three, "south" of the PMU. Needs a few mm of wire to reach
any place where one can put a capacitor, though. (The GND sides of
the small pair next to the MCU are good to reach.)
