I have been planing to do a project with Arduino Mega 2560 and 8 MPU-9150s + I2C Mux. I was just advised to have a regulator 5V -> 3.3V (for example, PCA9306, SparkFun Level Translator Breakout - PCA9306 - BOB-15439 - SparkFun Electronics ) for I2C, instead of connecting to 3.3V directly. Can someo…
