nRF52840 Configuration 4 VDD (Layout)

[Radio]

Hi All,

I am currently in the process of designing the PAB layout for my design. My schematic follows the reference design 4 recommended by Nordic. 

In this VDD_HV (From Battery) is connected to VDDH(Y2) pin of the chip. With this configuration, all the other VDD pins in the chip outputs 3.3V.

In my design I am using this VDD for different purposes such as to power a temperature sensor or LED etc.

My question is in my PCB layout, should connect all the VDDs lines together? 

Thanks!

Hi,

 

Yes, you should connect all the VDD pins together externally. This is the main supply of the nRF52840, connecting them together is needed to ensure that the nRF52840 has a nice and stable power supply.

 

Best regards,
