nRF52840 I/O level

[Daniel]

I was wondering what determines the logic level of the nRF52840 interfaces? Is it whatever you supply VDD with?

For example, if I supply VDD with 2.8V, will the logic level of the I2C interface or PWM interface be 2.8V?

Hi,

Please take a look at Electrical Specifications. The high output voltage is between VDD-0.4 to VDD.
