nRF5340 Audio DK GPIO level

[Lawrence_p]

Hi,

I'm trying to use an nRF5340 Audio DK to communicate with another board via SPI. The voltage needs to be 1.8v. How do I configure my board to do this?

I had the same question about GPIO voltage levels on the nRF5340 Audio DK, and the verified answer makes it much clearer. It's good to know the GPIO level already matches the 1.8 V VDD, so no extra configuration is required for interfacing with 1.8 V peripherals.
