    Intel Joule interface voltages (UART, I2C, GPIO)


      I cannot figure out what voltage levels the various communication interfaces can accept on the logic lines on the Intel Joule 570x.  I see that in general that there are 1.8V, 3.3V, and 5V buses, but I can't find anywhere in the documentation specifying what voltages the various interfaces can tolerate. I need to know if I will need a level shifter to communicate with my device.  I have checked the documentation for both the Joule module and the expansion board, but I can't seem to find this information.
