Coexistence pins

On the nRF9160 DK (Development Kit), there are three COEX pins enabling coexistence handling between multiple wireless devices. These pins are routed to the nRF52840 for use when nRF52840 is used as a network processor. These signals are also available on connector P1.

MAGPIO

The nRF9160 has an interface allowing the modem to control external circuitry through the MAGPIO pins. On the nRF9160 DK, MAGPIO0 is used to enable the Global Positioning System (GPS) Low-Noise Amplifier (LNA), while the remaining two MAGPIOs are not in use in this DK. The user can access MAGPIO1 and MAGPIO2 through test points TP2 and TP3.
