Overview
********

Octopus SoM is a System on Module (SoM) built around the nRF9160 SiP
offering NB-IoT and LTE-M connectivity, GPS and accelerometer.
It supports on board eSIM and external nano SIM connector. It's purpose
is to provide flexible hardware platform for IoT applications.

nRF9160 SiP contains ARM Cortex-M33 application processor and the
following devices:

* :abbr:`ADC (Analog to Digital Converter)`
* CLOCK
* FLASH
* :abbr:`GPIO (General Purpose Input Output)`
* :abbr:`I2C (Inter-Integrated Circuit)`
* :abbr:`MPU (Memory Protection Unit)`
* :abbr:`NVIC (Nested Vectored Interrupt Controller)`
* :abbr:`PWM (Pulse Width Modulation)`
* :abbr:`RTC (nRF RTC System Clock)`
* Segger RTT (RTT Console)
* :abbr:`SPI (Serial Peripheral Interface)`
* :abbr:`UARTE (Universal asynchronous receiver-transmitter with EasyDMA)`
* :abbr:`WDT (Watchdog Timer)`
* :abbr:`IDAU (Implementation Defined Attribution Unit)`

More information about the board can be found at the `Octopus SoM Product Page`_ and
in the `Octopus SoM Documentation`_.

Programming and Debugging
*************************

Norik Octopus SoM can be programmed and debugged using the exposed SWD pins.

Building an application
=======================

In most case you'll need to use ``octopus_som/nrf9160/ns`` board target for building examples.
Some examples don't require non secure mode and can be built with ``octopus_som/nrf9160`` board target.

Flashing
========
Refer to the instruction in the :ref:`nordic_segger` page to install and
configure all the necessary software.

Use the :zephyr:code-sample:`blinky` sample to test if Zephyr is running correctly on your board.

.. zephyr-app-commands::
   :zephyr-app: samples/basic/blinky
   :board: octopus_som/nrf9160
   :goals: build flash

Debugging
=========
Refer to the instruction in the :ref:`nordic_segger` page for information on
debugging.
