BSOM B404X Base Board Voltages

I am building a base PCB for the B404X. Two questions:

  1. Is VSYS on the M.2. pinout the same as the 3.7V Bus?
  2. Is the node in the red box below VSYS and 3.7V?

Thank you.

Yes. Unfortunately depending on what you're looking at, the cellular modem power could be 3V7, VSYS, or VCC.
