nRF7002 DK v1.0.0

VDD power sources

The main supply (VDD) can be sourced from the 5 V domain.

For the 5 V domain, there is one fixed 1.8 V buck regulator and one voltage follower regulator that follows the VIO_REF voltage

The power sources are routed through a set of load switches, which is controlled by logic to prioritize the power sources in the correct manner.
