And did you go further than thinking about it :-)? I have used the ATECC5/608A with a samr21-xpro and a nucleo-f410rb so far, worked like charm.

Haven't used it so far. Check out the PR that introduced it #11240. Otherwise, there are many I2C address scanners around that can be run on different analyzers, just google a bit.

So you don't have an "official" breakout board available for reference? What are the I2C pins on the nRF52832? Did you use the development board from Nordic? Did you consider pull-ups on the I2C lines, does the Nordic have "strong-enough" ones?

@Einhornhool can you try this configuration?
