nRF7002 DK v1.0.0

Power sources

The nRF7002 DK has a 5 V boost regulator.

It gives a stable 5 V output from the following four possible sources:

Each source has a reverse protection diode to prevent current flowing in the wrong direction if multiple sources are connected at the same time.

Reverse protection is not applied if the SW10 switch is moved to Li-Poly. In this case, the power is routed directly to the VBAT of the nRF7002 DK. Care must be taken not to apply an external voltage in reverse, as this might damage the DK circuitry.
