I plan to use this OLED display that has the following spec:
from the seller: Type OLED Display Interface I2C LED Colour White Resolution 128x64 Viewing Angle 160° Power Consumption 0.08W Voltage 3-5V DC Working Temperature -30 to 70°C Driver IC SSD1306 Dimensions 27x27x4mm
Now, most of the time I will use UNO that uses 5V logic. In which case Vcc=5V and both I2C lines are also matching 0 to 5VDC levels.
My question is - what will happen to the display if I try Vcc=3.3V but the I2C logic be of 5V? Can I mix the two voltage levels safely?
