Open AN11276- Class_4 - Class_4.brd file with Allegro

I chose "wireless connectivity" please let me know what the approriate location for this quesiton is.

I am trying to open the NFC antenna design Class_4.brd. to then integrate it with NHS3152.

I can open it in Fusion360: however i want to check that the dimensions are correct:

Foloowing on from : Solved: Re: How to open Board layout (.brd) for MIMXRT1060... - NXP Community

I downloaded Allegro Free Physical Viewer, and tried to open the file:

Howver I am getting a corruption error:

ERROR (SPMHDB-238): The design is corrupted. It may have been copied from a different architeture using ASCII mode; copy using binary mode.

Is there an issue with the class_4.brd file ?

Can you confirm the dimensions of the antenna (or where i can find them)

Thanks,

Leo

Hello Leo,
Thank you for your interest in using our products.
I've successfully opened the Class_4.brd file using Autodesk Eagle and this didn't give me any issues or errors.
About the question regarding the measurements of the design, they are correct.
Thank you for taking the time of using our community!
I'm attaching my own printed screen.

Thanks @Fabian_R ,

I will then proceed to make the design from scratch in fusion360, this should work!

Last thing, with Class_4.brd and NHS3152 am I correct in believing that i can directly connect the antenna to LA LB for the NFC to work, without attaching any other capacitances/etc ?

thanks,

Leo

Hello Leo,

Sorry for the delay in answering back.

According to our design recommendations, it is not mandatory, but if you look at the next path, you must download the NHS3100 SDK

https://www.nxp.com/products/rfid-nfc/nfc-hf/ntag-smartsensor/nhs3100thadadk-nhs3100-starter-kit-for-therapy-adherence:NHS3100THADADK?tab=Design_Tools_Tab#documentsandsoftware

And after download and extra open the next path: ...\NHS31XX\release_mra2_nhs3100\release_mra2_12_4_nhs3100\docs\NHS3100 Temperature Logger

You will find the schematic, NHS3100_tempLogger_schematic.pdf

I hope this information has helped to design your application.
