I'm looking for an nRF52 development kit with the PCA10040 1.1.0 or 1.1.1 board and the revision 1 IC. Closest I can find is that SemiconductorStore (Symmetry) claims theirs is Rev C. As suggested in another question, I've asked different vendors (DigiKey, Mouser, and Arrow) which revision they have; the technical support people I've asked either don't know or say they can't guarantee a revision. The current SDK (12 at time of writing) doesn't support anything older than C, and to be more "future proof" I'd prefer a rev 1. (I have an 0.9.0 DK with eng. B.)
I am in the US. How can I order a 1.1.1 nRF52-DK with rev 1 IC? Do I have to blindly order and return dev kits until I find a vendor with the current one?
