    This kind of thing is very new to me so please excuse my ignorance. I am attempting to get this working with an atmega328, with this breakout running at 3.3v and the atmega chip running at 5v. I am a little worried about the need to level shift the I2C bus. I notice there are a couple of 10k pull up resistors on the schematic from SCL and SDA to VCC (3.3v) which I understand is a solution to making a 5v microcontroller handle the lower voltage I2C signal? Just wondering whether this will work simply by connecting the two together or whether I should implement something more concrete like the MOSFET type circuit I have seen around. Also does anybody know if the start-up procedures mentioned in the MPU6050 datasheet are crucial? I only just noticed them!

No public wish lists :(
