nRF5340 AUDIO DK external antenna

[Sergio Serrano]

Dear Nordic team

I'm evaluating nRF5340 Audio DK. Everything is working fine, but I'm wondering if is it possible to improve wireless range using an external antenna on J1?

If possible, are you so kind to let me know which reference should I buy? If you could provide a link will be very welcomed!

The connector is the same as used on the various DK's: https://infocenter.nordicsemi.com/topic/ug_nrf52832_dk/UG/dk/hw_rf_measure.html

You need a cable, Murata part no. MXHS83QE3000, that have a SMA connector in the other end. Then a 2.4 GHz antenna of some kind. Note that some have RP-SMA instead of normal SMA, those won't fit.
