Minimum required external components required for small PCB.

[Natalie]

Hi, I am designing a small PCB (18mm diameter) and would like to know what external components I can exclude for nRF52805/ nRF52811. I would like to not use the decoupling capacitors on VDD, DEC1,DCE2 and DEC4 as I have two 22uF decoupling caps at the battery input. Please advise thank you.

All components shown in the reference schematic are mandatory. If you leave any of them out, you will have no or reduced performance. The decupling capacitors are especially important and the values must be as in the schematic.
