NRF52840 DK USB connector J2 is broken

[EAkeila]

Hi,

I was working on nrf52840 DK and I left it a few weeks and came back to use it and I discovered that the whole USB connector (J2) got removed. Not sure if there are other pins on the board that I can use to interface with the PC or that's it for the board? With this current, I can still use it for something else? Thanks in advance

Hi Ehad,

You can still use the board however with the USB connector missing you cannot use the on board programmer or the on board TTL to UART interface.  However, the board can be  powered up using P21 with 3vdc.  If you have another development kit or J-Link programmer you can program the nRF52840 by connecting to the 10 pin Debug port located at P18.  you can also remove power from the on board programming chip by using the nRFonly switch.   At this point the Dev Kit is basically a big nRF52840 module.

I hope this helped.

Thanks a lot Jay. That should be good enough and thanks for sharing the details of the board. I can see that I can potentially fix the USB connector by soldering wires from the components back to the pins of the USB connector. I think I can this a try and see how it goes

Just in case anyone has the same issue, I have soldered wires from the following circled pins to the corresponding pins of an external USB cable.  Now the board is working again!
