CC2650STK: About scope of Declaration of Conformity

Part Number: CC2650STK
Other Parts Discussed in Thread: CC2650,

Hi Team,

About scope of Declaration of Conformity

Please help me answer the follow question from my customer, thank you so much.

I am using CC2650SenseorTag and would like to reduce the battery replacement.
This product has BAT+ and BAT- terminals on the board.
We want to operate with a battery box and a CR2 battery at the timing of battery exhaustion.
Could you answer the two questions below?
1. Is the use as described above out of the scope of the technical certification?
2. If No.1 is, is it a problem from the viewpoint of technical certification to use a power supply from other power source in the form of a coin battery(CR2032), without modifying the main body?

Best Regards,
Tom Liu

  • The certification is done with the product as sold. But what is the background for the question? If they want to test one sensortag in the lab with a different battery solution this is ok. 

  • Hi,

    Thank you for your answer. below is the detail about the question.

    [Background]
    CC2650 is operated at a location different from where I reside.
    When CC2650 runs out of battery, I have to go to another site just for battery replacement.
    In addition, the board of CC2650 has a part written as “BAT +” and a part written as “BAT-”, which seems to be a place to connect the battery from the outside. Therefore, we want to remove the built-in “CR2032” battery and connect the “CR123A” battery externally to “BAT +” and “BAT-”.
    * I mentioned "CR2" last time, but it was a mistake of "CR123A".

    [Concern]
    Because the battery uses the same voltage as the original "CR2032", I think that the actual radio wave contamination will not change.
    We recognize that even a slight modification to a device that will emit wireless signal may be outside the scope of technical certification.
    All we need to do to modify the device is to attach the battery box by soldering to “BAT +” or “BAT-”.
    If the main unit is not modified at all, I just insert an external battery that resembles the CR2032 battery in the place where the CR2032 battery should be inserted. I don’t want to make any changes to the main unit, so I think it’s okay.

    [Question]
    (1) Isn't there a legal problem if the battery box is soldered to "BAT +" and "BAT-" and operated using the "CR123A" battery?
    (2) If (1) cannot be implemented due to legal problems, CC2650 will not be modified at all. If I put a dummy with the shape of “CR2032” in the place where you want to put the default battery, and connect “CR123A” to the dummy, can I use it with technology certification?
    The images of (1) and (2) will be attached. Attached file: CC2650.jpg

  • Hi Tom,

    The CC2650 SensorTag is a TI Evaluation Board and is subject to the terms and conditions provided with the kit when you received it. 

    For your own development/experimentation and usage you are basically free to do whatever you want with the SensorTag. You cannot however include the SensorTag in an end product.

    Regards,
    Fredrik

  • Hi Fredrik,

    Thank you for your answer.
    But my customer still have a concern about this problem.
    My customer is a Japanese customer, so he think your answer were based on American law and what are the regulations in Japan?

    Best Regards,

  • Hi Tom,

    The CE DoC is applicable to Europe only.

    Connecting an external battery pack to the terminals on the SensorTag PCB will not cause any problems.

  • Hi Fredrik,

    Thank you for your answer and please let me ask you some further question.

    For CC2650, I can find “CC2650STK EU Declaration of Conformity (DoC)” in product folder, but where is the Japanese version? I think since the EVM is on sale in Japan, it should pass the technical certification in Japan.

    What is the regulation about customer use TI’s EVM board to their own product?

    Best Regards,
    Tom Liu

  • Hi Tom,

    The SensorTag has not gone through any RF certification for Japan. We are however testing all our products internally for Arib T-66 compliance.

    Note that the SensorTag is an evaluation board, it is not an end product.

    Regards,
    Fredrik
