nRF9161 DK Development kit

Cellular IoT development kit for LTE-M, NB-IoT, GNSS and DECT NR+

For new design projects we recommend selecting the nRF9151 DK

The nRF9161 DK is an affordable, pre-certified single board development kit for evaluation and development on the nRF9161 System-in-Package (SiP) for LTE-M, NB-IoT, GNSS and DECT NR+. It has a dedicated LTE-M, NB-IoT and DECT NR+ antenna that supports a wide range of bands to operate globally. The nRF9161 DK has the same coverage as the nRF9161 SiP. LTE bands B1-B5, B8, B12, B13, B17-B20, B25, B26, B28, B65, B66 and B85 are supported.

An integrated patch antenna for GNSS is also included on the PCB, while SWF RF connectors are available for measuring the performance of the RF signals. Both antenna connectors also allow for the use of external antennas.

All GPIOs and interfaces are available via connectors. The kit is Arduino Uno Rev3 compatible, meaning it can easily interface with external device shields, such as the nRF7002 EK, which can be used for Wi-Fi locationing. User-programmable LEDs and buttons (4 each) are available for output and input. 

The nRF9161 DK has both a nano/4FF SIM card slot and an MFF2 SIM footprint, to support plug-in and soldered (e)SIMs. The kit is shipped with a SIM card that is pre-loaded with free data. It also supports the use of Software SIM, further reducing power consumption.

Programming and debugging are enabled through the on-board SEGGER J-Link, which also supports programming and debugging external targets.

The nRF9161 DK is supported by a full suite of development software, tools and resources, including the Nordic Developer Academy’s Cellular IoT Fundamentals course. 

The nRF9161 DK comes pre-flashed with our Serial LTE Modem application for interfacing through AT Commands. Getting started with other firmware samples is available in the Quick Start tool, found in nRF Connect for Desktop.

DECT NR+ Firmware Binaries


The official DECT NR+ firmware binaries can be accessed by contacting Nordic Sales, check the changelogs for more information what the different version has introduced.

  • Changelog: MAC and PHY v2.0.0

     

    • This release introduces comprehensive DECT MAC (Medium Access Control) layer functionality, building upon the existing PHY layer capabilities.
      This release supports star network topology.

      This release supports: nRF9151 LACA A0/A1 SiP

      This firmware supports the "Release 2 of the DECT-2020 New Radio (NR) technical specification v2.1.1"

      DECT NR+ operation is enabled on frequency bands 1, 2, 3, 4*, 9 and 22. (*only on the nRF9151).
