Pin assignments

This section describes the pin assignment and the pin functions of the nRF9151.

The device provides flexibility when it comes to routing and configuration of the GPIO pins. However, for some pins there are recommendations on pin usage and configuration. See following table for more information about this.

LGA pin assignments

The pin assignment table and figure describe the assignments.
