Is the nRF52840 IC Revision Engineering B 100% pin compatible to Engineering A, i.e. pinning given in nRF52840 datasheet v.0.5.1 still valid?

But there is a one difference, and that is that revision B will not work without the connection between DEC4 and DEC6 as shown in the reference layout. 0.5.1 is valid for Revision B.</p> <p>There will be an updated Product specification when the product is released that will replace the objective product specification.
