changes that have been made to the BLE nRF5280 dongle PCB schematic and layout design

[Ahmed Salah]

Dear Nordic Semiconductors Team,

I am writing to inform you of the changes that have been made to the BLE nRF5280 dongle PCB schematic and layout design that were obtained from Nordic  Altium Designer files.

The changes made to the schematic diagram involved adding a battery holder component and removing USB components and other non-used components such as push buttons. were also adjusted to suit the new design. These changes were necessary to meet the specific requirements of our project.

Furthermore, we have also made changes to the PCB layout to fit the battery holder in the designated location. The dimensions of the PCB were adjusted, and the component placement and routing of the traces were modified to accommodate the changes made to the schematic diagram. Lastly, the BOM was updated accordingly to reflect the changes made to the PCB layout. 

NOTE, The coin battery to be used supplies a 3.3V as I am aware that the USB previously supplied 5V to power the ble device therefore I have modified resistor R7 value to be 0 ohms. please verify  

We kindly request your assistance in verifying the changes we have made to the device PCB. Please review the modifications we have made to the schematic diagram, PCB layout, and BOM to ensure that they meet the required standards and specifications.

Thank you for your cooperation, and we look forward to hearing from you soon.
kindly find the attached modified Altium designer zipped files 

Best regards, [Ahmed Salah ]

Dear Bendik,

Thank you for your prompt response and for pointing out the remaining unneeded traces and the incomplete connection of the VDD_nRF net. I have made the necessary modifications and have attached the updated design files to this reply.

Please feel free to review the files again and make any further modifications and revert or revisions as you deem necessary. I trust your expertise and attention to detail, and I appreciate your efforts in ensuring that the design meets all the necessary standards and specifications.

Thank you again for your help and support.

Best regards, Ahmed

Hi Ahmed,

There is still no connection between the battery holder and the rest of the VDD_nRF net, it seems like a via is missing here:

 

Other than this there board should be OK.

 

Best regards,

Bendik
