Hi, I'd like to drive an LCD characters display that uses I2C bus with 5V DC levels for SDA and SCL.
What voltage range is supported by the I2C connection of the UniPi1.1?
Is it 3.3V as per the Raspberry Sor is there a voltage level shifter to get/accept 5V DC on I2C pins?

@Giancarlo-Bazzi did you manage to set 3.3V as I2C voltage level?
