nRF52840 versions

[bonnet]

Hello,

We have received in april 2018 nRF52840 QFN packages nRF52840-QIAA-R marked as well QIAA-R-SAM.

We would like to know to which version they are related : A, B, C, D  QIAA-nA0 ?

We develop software with Demo Kit marked 18.03, is it the same version ?

And the Demo Kit 18.20 from which version are they ?

Answer is urgent.

Thank you

Hi,

All chips and boxes should be labeled according to:
http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52840.ps/ordering_info.html?cp=2_0_0_9 

You can find an overview of build codes here:

FYI: Engineering C and Revision 1 are identical, the only difference is that Engineering C was made prior to product have gone through our qualification and transferred to mass production. Engineering A and Engineering B are early hardware revision samples that was never intended for mass production.

Best regards,
Kenneth
