RE: nRF51822 and nRF6310 GPIO mappings

You're right! My problem is if you look at the nRF6700 user guide side-by-side with the nRF51822 DK user guide it seems like IO P1 goes to Ext B and P2 goes to Ext A. But they are mating connectors, so it mirrors.

nRF51822 P1 connects to nRF6310 ExtA and P2->ExtB

Thanks!

Hm, on the motherboard, the pins are like this:


nRF51822    <-> Motherboard
P0.00-P0.07 <-> P0.0 - P0.7
P0.08-P0.15 <-> P1.0 - P1.7
P0.16-P0.23 <-> P2.0 - P2.7
P0.24-P0.31 <-> P3.0 - P3.8

What you might be seeing is that the UART can be configured to different pins, and depending on what example you check (and what board you are using) the uart could be mapped to different pins.
