I am using the Nordic 52840 CSP for my project. It is used for a asset tracking application. I used the nRF52840 QFN schematic reference for design. Since there is a difference in the number of pins for the CSP and QFN; request you to kindly check the attachment and let me know if there are any changes to be made in this.

Hi,

 

• DEC5 shall not be connected to VDD.
• C3 should be NC
• Depending on what kind of antenna you are planning to use, you might need additional components for tuning the antenna to 50 ohms. C10, L3 and C11 should not be used for this. A full pi network is often needed in addition to these.

 

Other than that this looks good.

 

Best regards,

Andreas
