Difference between nRF85 PDK and nRF52840 DK, both seemingly being PCA10056?

[Elm]

Hi

Some time ago, we purchased a couple of boards, then (I believe) called nRF52 PDK. They are marked PCA10056.

We need to obtain more nodes. From gleaning information about them, it seems like the nRF52840 DKs have the same product number, PCA10056. Is this true?

Are these two boards types equal from a programming point of view?

Hmmm. After digging through my pile of old emails, I now realize that we bought nRF52840 PDKs (and not nRF52 PDKs.)

So, the new question is: Are the nRF52840 PDK and nRF52840 DK equivalent, from a programming point of view?

Also, are both called PCA10056?

Yes, both are called PCA10056. The nRF52840 DK uses IC revision 1.

Yes. The main differerence is the nRF52840 IC revision that is on the board. See this page. There are 3 erratas that are fixed from Eng.B to Eng.C/Rev.1. See this list.
