nRF52805 power supply

[PKaempf]

I wonder what external load (if any) can be connected to the VDD pin of the nRF52805. Reading the data sheet gives the impression it is for internal loads only, but I assume that limited use for e.g. sensors should also be possible. But I cannot find any limits.

All VDD pins are inputs on the nRF52805 so as long as your powers supply is up to it, you can connect whatever you like to VDD,

Hi Ketiljo, thank you for the quick answer. Sorry to ask again, but I would like to extend the question to the DCC pin. VDD is for supplying power to the chip, but what is the maximum load on the VDD pin?

[ketiljo]

The DCC pin can't supply anything else. The DCDC converter will only supply the radio peripheral.

Thank you very much, Ketiljo! As always, Nordic support is excellent.
