[VERSIONS] PN532 NFC/RFID controller breakout board

Post by jujujuijk »

Hi there!

I would like to buy this module for my Raspberry Pi:
https://www.adafruit.com/products/364

But I am wondering about the range of the antenna.
In the description you state: "New in version 1.3: ..."
And in many other websites they talk about a v1.3.

In the antenna design document:
http://www.adafruit.com/datasheets/PN53 ... n_v1.0.pdf
the table that gives information about ranges talks about a version 1.0 and 1.5.

My questions are:
What is version 1.5? Can we buy it or is the 1.3 the current release?
Does the v1.3 have the communication range of v1.0 or v1.5?

Thanks
Thomas

Nothing has changed in the antenna. We've had minor fixes for lower power improvements and silkscreen tweaks. The range, functionality, code, etc. is all the same.

Thanks for your answer but I am still confused about what I should consider as the range of the antenna of this module.

This is what the document of the antenna says (for a card): [pages 8-9]
Com. Range
Version 1.0: 38[mm]
Version 1.5: 77[mm]
The current module owns the enhancements of the v1.5 so its range is 7.7cm?
Or it didn't get that enhancement yet?

Oh that research document is from 3 years ago. v1.0 never made it out to customers. And we improved it since then, its at least 8cm for any shipping product we ever sold.
