I am designing a custom carrier board around the Jetson Nano Module. I am trying to figure out if the module has internal pull ups and/or level shifters for the 1V8 pins, or even if these are indeed 1V8 logic level pins? It seems there’s just some ambiguity from the datasheet which looks like these pins are 1V8 logic levels, but also that they have internal pull ups. Can someone help specify this?
To be more specific, I am trying to figure out if the UART/GPIO/I2C pins of the Nano are 1V8 and if they require external level shifters to read data from 3V3 or 5V signals?
