nRF52840 DK availability

[vard]

Quick question: when will the nRF52840 DK available? On the nRF52840 DK page, there is a recommendation to avoid the PDK: 

"The nRF52840 replaces the nRF52840 PDK which is not recommended for new designs." but no distributor has any DKs in stock, only PDKs.

Thank you!

Hi Vard, I have the same problem. 

I'm sure here we can find out why is not recommended and if  is suitable for our needs and we can use it anyway to evaluate the product till the DK is available on the Italian market.

Thanks in advance guys for your help

The DK should be available soon, if I am not mistaken the first batch should already be produced. The main difference between the PDK and DK is that the DK uses the final production version of the chip, while the PDK uses an engineering sample.

PDK, Revision 0.11.0 uses engineering revision B, chip marking BB0.

PDK, Revision 0.12.0 uses engineering revision C, chip marking CA0.

DK, Revision 1.0.0 uses Final silicon, chip marking C00. Some layout changes compared to PDK.

You can find the changes between Rev B and Rev C here. As you can see there is not a lot of changes, so as long as you are aware of the changes you can use the PDK for Evaluation/Development until the DK becomes available (not sure about the delay from production until it reaches our distributors).

Thank you kindly for your response, I think I will wait for the DK to become available.

run_ar  Thanks a lot.

Last question: where can I buy the PDK, Revision 0.12.0 uses engineering revision C, chip marking CA0.

I've checked on mouser,Rs,RF and arrow but the only one that specifies the version is Components-shop online and it's 0.9 version or Mouser that says version 5.

Can you send me a link of distributor selling the 0.12.0 version.

Thanks

I am afraid you need to check with the distributors which version of the kit they are selling if this is not stated on their web page. I am really sorry for the inconvenience.
