NXP's NTAG I²C plus kit suitable for any boards featuring an Arduino-compatible header, including LPCXpresso, Kinetis and i.MX boards. It is designed to emulate using an  NTAG I²C plus kit tag chip in an embedded electronic system.


  • Arduino compatible pin headers
  • NTAG I²C plus antenna board mounted on an adaptor board with an Arduino-compatible header.
  • Bluetooth pairing example based on NXP KW41Z
  • Projects available on Explorer Kit moved to Kinetis platform (e.g. pass-through mechanism)
  • Library for  NTAG I²C plus kit available through MCUXpresso for FRDM-KW41Z


FRDM-KW41Z - Development Kit (included in this roadtest)

The FRDM-KW41Z is a freedom development board for Kinetis KW41Z microcontroller with 2.4GHz BLE, generic FSK and 802.15.4 wireless connectivity solutions. Integrating Bluetooth Low Energy (BLE) v4.2, generic FSK (at 250, 500 and 1000Kbit/s) and IEEE 802.15.4 compliant modem, Kinetis KW41Z MCUs can support multiple protocols running concurrently (time slice) in a single chip. This MCU is also integrate a buck boost DC to DC converter supporting a wide range of operating voltages from 0.9 V to 4.2 V, significantly reducing the peak current in receive and transmit modes. At the same time, this MCU family delivers an excellent link budget that ensures the longest range of communication and high immunity to interference.

  • BLE v4.2 host stack and application profiles
  • Generic FSK at 250, 500 and 1000Kbit/s
  • 802.15.4 MAC/PHY support
  • Thread network stack
  • Support for host MCU and MPU (Linux) processors
  • Support for IAR embedded workbench and Kinetis design studio (KDS) IDEs
  • Full integration with Kinetis SDK
  • Multiple reference designs
  • Support for multiple RTOS including FreeRTOS

Comment List
  • All accounted for here!

  • All present and correct here. There should be two KW41Z boards and the I2C shield, as per my photo.

  • gordonmx






    Is anyone missing from their kit a FRDM-KW41Z development board?





  • Thanks Randall


    I am looking forward to this RoadTest. As says, it's a great combination  - NTAG I2C board with a FRDM-KW41Z development board.

  • The following applicants were selected as official roadtesters:







  • To all applicants,


    I will be pasting the 5 official roadtesters in a few minutes.


    But I wanted share something from an applicant that was not selected as an official roadtester. He said his testing procedure was:


    2) check for highest voltage it can withstand

    3)how much current it can handle

    4) temperature test

    5) how much useful they are for my projects


    He also said he was a beginner.


    Now, let's take a look at these 4 points:


    2) check for highest voltage it can withstand --- think about it guys: This product enables NFC capabilities. It also takes advantage of energy harvesting. If those are facts, then why would a voltage withstand test be important? (Granted, you zap the thing with 100V of course it's going to down.) This kind of test has little to do with this product. either the person is a beginner and doesn't understand the product, so I suggest reading this to get the basics element14 Essentials: Wireless Protocol III or the applicant did not look over the documentation. No one expects all roadtesters to be experts, but it took me all but 3 minutes to look up the docs. Engineering has a lot to do with looking before leaping into anything.


    3)how much current it can handle --- see above point. But is this worth testing for? Plus, does the product have overcurrent protection circuits anyway. I don't know off the top of my head.


    4) temperature test-- I would agree with the applicant. I think a temperature test is a valid test. But I looked up the datasheet and in 30 seconds I found the spec: Temperature range from -40 °C up to 105 °C  Not the widest but pretty darn good! An ample range for operating anywhere from Antarctica to the equator! Plus a lot of industrial environments. The question is: can a roadtester actually do a valid temp test. But is this the most important kind of test to do. No. The applicant needs to go back to the drawing board.


    5) how much useful they are for my projects -- yes, this is interesting. Adding NFC capabilities to a lot of electronic projects would be FANTASTIC! I would love to have more projects on element14 that leverage NFC. But the applicant did not expand on it. I know there's an older version of an NFC expansion board for the Raspberry Pi. But the NTAG I2C plus is much, much better. This could have been the entire roadtest: add this to a single board computer and tell me what you did and what you think.


    I'm giving you feedback not to embarrass but to help you be the best you can be for this roadtest.

  • I was wondering why the enrolment keeps restarting.

  • Need one more good applicant who knows something about NFC.
