Icarus SoM DK
Overview
The Icarus SoM DK is a single board development kit for evaluation and development on the Icarus SoM (Icarus SoM Docs [4]). The Icarus SoM features the nRF9160 SiP from Nordic Semiconductor, a low-power 3-axis accelerometer and an on-board eSIM. The development kit provides interfacing to the SoM through USB-C, a set of user LEDs, a reset and a user button, a battery charging port, and a external nano SIM connector. The board is also Arduino Uno Rev3 compatible which makes using external shields possible.
The main uController is the Nordic Semiconductor nRF9160, with ARM Cortex-M33F CPU, ARMv8-M Security Extension and the following devices (provided directly by Nordic):

SIM selection
The sim choice (eSIM or nano-SIM) can be configured in Devicetree by adjusting
the sim property in the sim_select node.
Security components
Building Secure/Non-Secure Zephyr applications
The process requires the following steps:
Build the Secure Zephyr application using
-DBOARD=actinius_icarus_som_dk.Build the Non-Secure Zephyr application using
-DBOARD=actinius_icarus_som_dk/ns.Merge the two binaries together.
If you are using Segger Embedded Studio v4.18 or later, the two binaries are built, merged, and burned automatically, unless you have disabled the feature.
When building a Secure/Non-Secure application, the Secure application will have to set the IDAU (SPU) configuration to allow Non-Secure access to all CPU resources utilized by the Non-Secure application firmware. SPU configuration shall take place before jumping to the Non-Secure application.
More information can be found in the Icarus SoM Product Website [2], the Icarus SoM DK Product Website [3] or the Actinius Documentation Portal [5].
