Setting the VREGHVOUT to 3V in the nrf7002DK

[Agus]

Hi,

I am trying to set the VDD pin to 3.0V instead of the current 1.8V (also changing the GPIO voltages to 3V). I've seen many questions related to that but no solution worked out. I have changed the register of VREGHVOUT, from the nrf5340, by using this command: 

nrfjprog --family nrf53 --memwr 0x00FF8010 --val 4
Parsing parameters.
Writing.

I also checked it and the register value has changed.

nrfjprog --family nrf53 --memrd 0x00FF8010
0x00FF8010: 00000004

What else can I do? Is it possible that the Vreg pin is not available in the nrf7002DK? 

Thank you,

Agustín

Hi Agustín,

 

Due to this errata, 3V GPIO voltage is unfortunately not available:

Kind regards,
