Hardware compatibility between nRF51422 and nRF52

[mstanisz]

Hi,

I currently have a custom board with an nRF51422 on board.  I am considering upgrading to the nRF52 series.  Are there any nRF52 models that are pin compatible that I could easily migrate to from an nRF51422 in hardware?

Best,

Matt

nope, redesign is required.
