How to set VDD output voltage in nRF52 Dev board based on nRF52832?

[Vid!!]

I am using nRF52 dev kit based on nRF52832 (PCA10040). Is it possible to set the VDD output voltage to 3V or 3.3V in this? If yes, how and what header files should be added to the project for this purpose? 

I know that in nRF52840, we can do this by setting the NRF_UICR->REGOUT0 register to UICR_REGOUT0_VOUT_3V3.

I want to set it to 3.3V actually and I saw it is mentioned in this nRF52 DK hardware desc page that "The 5V from the USB is regulated down to 3.3 V through an onboard voltage regulator.” But when I powered the board via USB and measured the voltage on VDD, it is around 2.9V. So how can I set it to 3.3V? Kindly suggest your valuable insights.

Hi,

It is not possible to adjust the VDD voltage on the nRF52 DK unless you supply it externally. That is because the voltage out of the external regulator on the DK is fixed, and there is no internal high voltage regulator on the nRF52832, unlike on the nRF52840.
