[nRF52840] Trace routing via D+ or D- pins.

[Krzysztof Rosinski]

Hello,

Is it possible to route GPIO trace via D+ or D- pin when USB is not used, please? We have VBUS connected to GND.

Kind regards,

Krzysztof

Hi Krzysztof,

My initial thought was also to reply "Probably not". I have now checked with other team members who say it is not recommended. VBUS, D+ and D- belongs to a different power domain than the GPIOs and also have internal hardwired circuitry.

Best regards,

Thank you, that makes sense.
