Okay, I will find another solution.

Perhaps a modification for the incoming new development kit to provide ?

Thanks

No, the pins aren't routed out from under the nRF5340 used as the interface MCU on the nRF52840DK

If you want to take a closer look at the hardware the nRF52840DK design files can be found here:

Hi,

Thanks for this answer.

Is there a way to connect the UARTE1 port to the VCOM1 interface MCU making some hardware modification on the nRF52840 DK board ?

Thanks.

Hi,

This is unfortunately not possible to do, as VCOM1 pins of the interface MCU is not connected to the nRF52840DK. The reason for the DK showing two COM ports when connected to a computer is that the same interface MCU is used on the nRF5340DK where both VCOMs are connected to the nRF5340.

If you need another serial connection on the nRF52840DK you need use a standalone USB to serial adapter.

Best regards,
