nRF93M1 DK Development kit

The fastest way to evaluate and build on the nRF93M1 — innovate faster

The nRF93M1 Development Kit (DK) is the ideal starting point for evaluating the nRF93M1 and prototyping your Cat 1 bis connected cellular IoT application.  

The nRF93M1 DK pairs the ultra-low-power nRF54L15 as a host MCU with the nRF93M1 so you can also prototype and develop your embedded application rapidly  nRF Connect SDK and Nordic’s AI assisted development flow.  

The nRF93M1 DK is flexible and also works with any other embedded or rich-OS host via the direct AT command interface, PPP, or USB — so you can prototype your preferred way. It works out of the box, with a pre-loaded Onomondo SIM card and LTE antenna included.

Key Features

  • On-board nRF93M1 LTE Cat 1 bis with Wi-Fi and cellular location
  • nRF54L15 as host MCU and AI assisted nRF Connect SDK development flow support
  • Pin headers, buttons and USB-C interfaces for easy evaluation and development 
  • On-board SEGGER J-Link debugger and programmer — flash and debug over USB-C
  • Flexible SIM (nano/4FF + eSIM), with pre-loaded Onomondo SIM card and LTE antenna in the box 

Develop your Cat 1 bis cellular IoT solution faster with AI assistance

The nRF93M1-DK and documentation are supported by Nordic's AI-assisted development flow. Connect your preferred AI assistant to the Nordic MCP servers for validated nRF Connect SDK documentation, API references, device configuration and nRF Cloud field data — from first prototype to deployed fleet.

In the box

  • nRF93M1 Development Kit board (on-board nRF93M1 + nRF54L15 host)
  • LTE antenna
  • Pre-loaded Onomondo trial SIM card 

 

Quick start

Set up your kit in five steps (see the full Getting Started guide for detail): 

  1. Assemble — attach the antenna, insert the SIM, connect USB-C to your PC. 
  2. Install tools — nRF Util and nRF Connect for Desktop; 
  3. Verify — send AT (expect OK) and confirm the nRF93M1 modem firmware version. 
  4. Connect to the network — enable registration reporting, set CFUN=1, and test connectivity. 
  5. Connect to nRF Cloud — register your account and provision the device, then add it under Fleet → Devices.

Highlights:

Maintenance release with new features, corrections, and improvements for service reliability.

NTN / Cellular IoT

  • Smarter cell selection. The modem now scans frequencies to identify and select the best-quality cell, configurable via AT%FEACONF (id 8). To optimize the search time with the feature, it is recommended to limit the number of bands (AT%XBANDLOCK) and/or channels (AT%FREQRANGES).
  • Faster roaming search. Improved network search speed with certain SIM subscriptions abroad.
  • Reduced AT notification load. %MDMEV: DETECTED COUNTRY changed from an informational to a regular event.
  • Automatic profile cleanup after FW update. Existing cellular profiles are now deleted automatically to avoid format compatibility issues. Applications should verify profiles exist before use and re-create them if needed.
  • Improved NTN reliability. Fixed premature attach-context expiry and prevented dropped NB-IoT uplink messages on power-off after transmission.
  • Greater modem stability.  Resolved rare crashes and instabilities.
  • Better PLMN selection. Fixed indefinite stalls during manual AT+COPS selection and restored missing %MDMEV SEARCH STATUS 3/4 indications.

A complete list of new functionality, changes and bug fixes is in the release notes found here or inside the .zip file.

This release is aligned with v1.2 of the nRF91x1 NTN AT Commands Reference Guide.

Some of the new features require support also from the nRF Connect SDK, and it is recommended to ensure compatibility with the appropriate version of the SDK.

It is advisable to use the latest version of nRF Connect for Desktop and nRF Connect Programmer tools.
