RE: NRF52833 PCB Layout

Sorry for the late follow up.

Everything essential should be available from the outer pins.

Reset could also be initiated from a physical power cut like a button(more about reset for nRF52833).

The reference design for nRF52833 also shows aQFN73 with only outer pins, without via in pad:

Here is a project where via in pad was avoided and reset was routed out.

Let us know if anything is unclear.

Please also remember that you may send us the design for review when you are ready.

Best regards,

Håkon

Hi,

I have seen solutions where this has been done for nRF52840. I will check if there are any issues to be aware of. One solution might be to route AC13 via one of the outer pins. I will look closer and get back to you by the end of the week.
