TI HRM smart watch

Hi,

I am working on TI opitcal HRM design files available at http://www.ti.com/tool/tida-00011. May be this could be a naive question but want to clarify on this from experts on this forum. The link below quotes HRM BOM.

http://www.ti.com/general/docs/lit/getliterature.tsp?literatureNumber=tidr099&fileType=pdf

But how do I place order for this BOM in a single go than to place order for each component individually ?

Any comments or inputs would be highly appreciated.

Thanks

  • Hi Srinath,

    All of the TI components from that design are listed under the TI Devices section of that page: http://www.ti.com/tool/tida-00011#tiDevice

    For each one you can click Sample & Buy, and it will take you to the page for the particular device, where you can choose sample, or buy from distributor (options may be different on different devices due to availability). I'm not sure what happens for all of the different distributors, but I know that with the free samples you can add them all to your sample cart on the TI website before you actually "check out". You bring up an interesting point though - it might be nice if we had a way to click one button and it would load your cart with all the TI devices for that design - I'll make this suggestion, but I'm unsure how feasible it will be to add this feature simply because I'm not sure if all of our distributors will carry all of the parts in one design, or some may be low on stock, etc.

    For other components listed in the BOM of the design that aren't manufactured by TI, you'll have to find distributors that carry those parts.

    Hope this helps,

    Katie

  • Hello Katie,


    Thank you very much for the reply. Yeah, I agree that it would be great if I can load all TI devices in a single go.

    Also it would be great if I can load all remaining non TI devices (such as caps, resisitors etc) in to my cart in a single go through either TI website or distributors. As product manageer, I have been spending nearly 4 days to fill up my BOM requirement and it has been increasingly difficult to track the components.

    Is there an alternative to fix this ?

    Thank you,
    Srinath

    To buy resistors and lightbulbs from TI? ROFL. Nice one :)

    That's life of material purchase managers :)

    Have a contract manufacturer build your boards for you.

  • Katie,

    Thank you for your response. Also on the same page (http://www.ti.com/lit/ml/tidr098/tidr098.pdf), I have TI HRM schematic in pdf. But the document is so blurry that, I couldn't read the component values or names. Can we have a neat and clear document so as to help my self for any further clarification  ?

    Appreciate your comments.

    THank you,

    Srinath

  • Hi Srinath,

    Thanks for pointing this out - I can see that the http://www.ti.com/lit/pdf/tidr098 schematic in the PDF is blurry. I will provide this feedback to the document owners so that it can be updated.

    In the meantime, you could also look at the actual schematic and layout files (instead of the PDF picture of the schematic) by getting the Gerber download from the same page: http://www.ti.com/lit/zip/tidc057. You can find this from the TI Designs page http://www.ti.com/tool/tida-00011 by clicking the "Design Files" button and then selecting TIDA-00011 Gerber under "additional design files". If you need a viewer for these files you can click "Get Viewer" Hopefully with that you should have all of the information you would need about the schematic and layout of the board.

    Regards,

    Katie

  • Kaitie,

    Thank you very much for the reply. I request you also to look in to below schematic files as well

    1) Pulse oxie based smart watch  (technically same as HRM)

    2) Body weight scale reference design with Body composition capability and BLE (Same as Hand to hand body composition meter reference design)

    We believe, schematics are more important  for board assembly than to look in to gerber files. Please comment.

    I also have the reference design files (as pointed by you) and supporting softawre paproved by TI for internal testing and evaluation purpose.But I couldn't find where to request PC or ipad ( or android ???) TI HUB  source code or software which collects data from above devices.

    We are a startup company focused on this internet of things theme with primary focus on healthcare. If you need additional information in providing us this HUB software, please let us know. I shall be more than happy to take this offline and follow up.

    Appreciate your time in responding to this email. Looking forward to hear from you.

    Thank you,

    Srinath

  • Hi Srinath,

    I have submitted a request for the PDF with the schematic to be updated as I mentioned before, but this may take some time. I'm hoping that in the meantime the other design files will be useful so that you are not stuck waiting.

    Schematics are definitely useful - the schematic file is included in that Gerber download I pointed out before, not just the layout files. If you download and unzip it, it is under HRM Board SCH Layout database, I'm able to open the .SchDoc files and view them in Altium viewer, and this is the source schematic that the PDF is made from, so you should be able to zoom in and see everything. I have notified the team to update the PDF as well though.

    On the TI Design page for the HRM wristwatch, if you scroll down to "Software" you will see a link for TI Health Hub Evaluation and Demonstration Software Request. This will give you a form that you can complete to request this software.

    Regards,

    Katie

  • Kaitie,

    Thank you very much for your quick reply. I shall go through the .sch file as mentioned by you. Also I hope you made similar requests for other designs as noted above.

    I made request though that  link, I got the micro controller source code only. I believe to fully evaluate the TI HRM and other smart watch based applications , we need demo software which can be run on an ipad as showin below in youtube video

    http://www.youtube.com/watch?v=rNknE9CvCD4

    If you could let me know, where to request the demo ipad software, It would really help us to get through our evaluation time.

    Appreciate your time in responding to this email. 

    Thank you,

    Srinath

  • Hi Srinath,

    I asked our team that owns these designs and unfortunately they said we cannot provide the iOS app source code or app at this time - I'm really sorry about this. If I were you I would try to get hold of a local TI sales contact or TI distributor sales contact to see if they could arrange a demonstration for your company or something.

    Regards,

    Katie

  • Dear Katie,

    I still see the PCB schematic files are not updated. Could you please help me in updating the same ?


    Thank you,
    Srinath

  • Hi Srinath,

    I submitted a request right after your first post. I'll follow up with the owner of this design to see when this will be updated.

    Regards,

    Katie

  • Hi Srinath,

    They sent me a new version of the schematic: 7140.HRMPOx_MSP430_AFE4400_BLE.pdf

    This is still in work to get it up on the website, but I wanted to make sure you could get a copy.

    Regards,

    Katie

  • Katie,

    Thank you so much for your help on this. Just as follow up on BOM, what does DNI mean ? In TI HRM BOM, I see for DNI coloumn, some rows are mentioned as Y and some are N.

    Please comment.

    Thanks

  • DNI means "Do Not Install". It is used to indicate parts which have pads on the circuit board but are not actually installed/soldered to the board. Usually used for optional components, jumpers, etc.
