      Is there a way to set 3.3VDC as I2C voltage level on UniPi 1.1?
      I can see that there is some I2C configuration header, but I can't find any information about it.

      PS. I've seen https://forum.unipi.technology/topic/467/unipi1-1-and-i2c-voltage-levels, but it is quite old and there is no answer.

        Hello,

        The I2C port is permanently connected to 5V and cannot be changed.
        For the UART port, it is possible to change between 5V and 3.3V using a jumper (JP6).

        Best regards,
        Antonin
