Other high speed gpios should also be possible to use, the reason the DK use somewhat different pins than recommended in the OPS is simply because the designer wanted to have access to trace and pin reset when using QSPI.

We recommend to follow the guidelines in the OPS in terms of choice of QSPI pins as far as possible due to internal layout.

Hi Jorgen,

When you say "other gpios", do you mean any high speed gpios or all gpios?

Hi Mickael,

The QSPI pins in the OPS are recommended pins, due to internal layout. We have not yet seen any issues with other GPIOs for QSPI, so you should be fine using the layout from the nRF52840-PDK.

Best regards,
Jørgen
