Good day all,
I have a 5 volt I2C device that I want to use with my pi. Am I able to pull the bus up via resistors to the 5-volts that my device runs off of, or does it need to be 3.3 volts? If it must be 3.3v, can I just create a simple voltage divider from my 5 volt rail?
I guess the big question is, does it matter what voltage I tie my I2C bus to when using the rpi?
