Can you help me check if it is right that the wires connect to the nrf52840 chips?

Hi Team,

I try to design a PCB based on nrf52840 chips, can you help me check if it is right?

Something like Power supplement, SPI interfaces, and debug and programming interfaces etc.

Hi Marjeris,

Do you know where to download CADs of nrf52840 chips?

With best regards,

You can download the nRF52840 QIAA reference layout from the nRF52840 product page on nordicsemi.no under the tab 'Compatible downloads'.

The files are Altium files. If you don't have an Altium license you can use use a free 6-months trial of Altium Viewer to review the files. And PDFs are also available in the downloaded folder.

Could you help me review it again?

With best regards,
