NRF52840 Dev Board

[DaveC]

The Dev Board has a connector J1 to connect an external aerial, I want to check the long range BLE feature.  Are there any PCB modifications required to the PCB to use this connector or is it just a case of attaching an external 2.4GHZ antenna?

Just insert the cable. There's a switch in the connector that will break the connection to the antenna. https://infocenter.nordicsemi.com/topic/ug_nrf52840_dk/UG/dk/hw_rf_measure.html
