nRF52840-DK Power Switch SW8 physically is broken

[avchizhov]

Greetings to everyone.

We have the nRF52840-DK, where the Power Switch SW8 physically is broken.

Is there any way (a bypass, making a bridge/shortcut, using a soldering) to make it powered on, i.e. permanently?

It is supposed, that the DK will be powered with the USB port J2.

We are appreciate for any suggestion.

Hello Anton,

Did it break in your hands or did it arrive in this state?

The link to the HW files is here: https://nsscprodmedia.blob.core.windows.net/prod/software-and-other-downloads/dev-kits/nrf52840-dk/nrf52840-development-kit---hardware-files-3_0_3.zip

You'll find it under the "Download" section on the page here: https://www.nordicsemi.com/Products/Development-hardware/nRF52840-DK/Download?lang=en#infotabs

You can have a look at the HW files as you can remove the switch and permanently have it ON if that it ok with you by making the connections under the switch with a small wire and solder. You can power the kit through the "External supply" pins between the white J6 and the USB connector as well.

Best regards

Asbjørn, servus.

Thank you for your answer.

Should we reffer to the PCA10056_Schematic_And_PCB.pdf?

Should we reffer to the nRF52840 Development Board - Power Supply drawing on the page 6?

Should we reffer to the drawing Power switch?

Hi Toni,

the power switch drawing is the right one. The PCA10056 is the board ID for the nrf52840 development board. I think all three of your questions regarding which you should refer to is correct.

Do you have the equipment available to remove the broken switch and short he connections?

Best regards
