The nRF52840 Dongle features a USB-A-type connector printed on the circuit board.

Additional test points for the USB data lines are available on the bottom side of the circuit board if the nRF52840 Dongle is used as a module on a motherboard with a USB connector. To disconnect data lines from the onboard USB connector, cut solder bridges SB3 and SB4.
