nRF9160 module
The nRF9160 SiP module consists of the nRF9160 System on Chip (SoC), power management and RF front-
end section, and passive and clocking components. External to the module are supply source (battery or
mains), SIM solution, and any customer peripherals and sensors. For further details of blocks and their
software controls and dependencies, see nRF9160 Product Specification.
