Preliminary

2.2. GPS Receiver Input Connector

A µ.FL conenctor (J1) is provided for user to connect to an external GPS antenna. J1 is connected to GPS receiver

input port of nRF9160.

The receiver supports GPS L1/CA reception. In Nordic’s white paper “nWP033- nRF9160 Antenna and RF

Interface Guidelines”, it is recommended to use active GPS antenna with LNA gain >15dB.

A 3V supply is provided to power external active GPS antenna via J1. It can be enabled via setting MAPGIO0 (pin

55 of nRF9160) to high. User may refer to “nRF91 AT Commands” for detail programming of this pin.

2.3. INTERCONNECTS BETWEEN nRF9160 AND nRF52840

Some interconnecting signals between nRF9160 and nRF52840 had been provided to aid communication/control
