Evaluate UWB interoperability with Apple® and Android™ mobile devices


The first evaluation kit offering UWB interoperability against Apple® and AndroidTM mobile devices.

Kick-start the design of your innovative applications by leveraging on the sample iOS and Android applications developed by MobileKnowledge and unleash UWB ability to create more precise, spatial-aware application experiences.

UWB technology is rapidly expanding into the IoT ecosystem.

Smartphones play a significant role in driving the adoption of UWB in the IoT ecosystem as they make the technology intuitive and accessible to a broad user base.

Get ahead of this trend and start evaluating how NXP's UWB TrimensionTM technology interacts with UWB-enabled Apple® and AndroidTM devices.

With the MK UWB Kit Mobile edition 2.0:

  • Experience how to establish a UWB ranging session between a UWB-enabled Apple® or AndroidTM smartphone and a UWB anchor or UWB tag based on NXP's TrimensionTM UWB IoT ICs
  • Leverage on the background operation mode for mobile devices to build hands-free interactions with nearby smart objects.
  • Obtain the MK UWB Connect application source code for Apple® or AndroidTM devices as well as the reference source code for SR150 UWB Anchor and MK UWB Tag software to interoperate against mobile devices.
  • Receive exclusive support from MobileKnowledge to accelerate the evaluation and development of UWB technology-based solutions.


The MK UWB Tag provides accurate positioning capabilities in an extra small form factor. It is Ideally suited for low-power applications thanks to Murata’s Type 2DK, an all-in-one UWB + Bluetooth® LE combo module which integrates NXP Trimension™ SR040 UWB Chipset:

MK UWB 3D Antenna board

UWB Module-compatible PCB that can be easily connected to the MK UWB Shield 2 supporting 3D Angle of Arrival measurements.

Ready-to-use solution that features three PCB antennas, enabling ranging, 2D, and 3D Angle of Arrival measurements as well as TDoA.
It can be easily connected to MK UWB Shield 2 and 1v3 using the board pin headers. Specific software and documentation is provided.

Now integrating Murata Type 2BP UWB Module!

Murata Type 2BP UWB SR150 Module

Murata Type2BP is the world’s smallest UWB module and includes NXP's SR150 UWB chipset. It is FiRa certified and is ideally suited for deployment in both larger infrastructures (indoor positioning anchors) and in consumer products and general IoT devices with battery operation.

This UWB Module regroups the core functionality of the UWB solution (clocks, filters, switches and passive components). Compatible with secure UWB ranging, 2D & 3D Angle of Arrival, and TDoA. Suitable for Anchor devices.

MK UWB Shield 2

Flexible platform to develop customized UWB systems. As the central part of the UWB Kit, it is used as the interface between the UWB module and external devices. It can also be plugged to any external host thanks to its Arduino-compatible expansion headers.

MK UWB Shield 2 gives support for FiRa-compliant secure ranging through SE051W.
