Hello,
I am attempting to connect a ST7789 to the nRF9161 and communicate with SPI. However the display is not working and I suspect it is because the gpios output the VDD voltage which is 1.8v. How can I change it to 3.3v?
Thanks.

If you're using nRF9161 DK, you can change the VDD_GPIO voltage with the "Board Configurator" app in the nRF Connect for Desktop.
Note: update the board controller firmware to 1.1.0 (or higher, if available), the voltage settings may not work with older firmwares. See:
nRF9161-DK - VDD Setting in Board Configurator does not work - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com)
This works. Thanks.
This works. Thanks.
