It seems the 9 axes shield uses I2C, a reset pin and several other pins for the TinkerKit Input, Output and TWI connectors. Does anyone have a list of specific ports used by the shield on the Arduino UNO?
It also seems that my Arduino UNO r1 only has the original analog pins for I2C, while the 9 axes shield uses the new pins next to the digital pins.
update: I asked support from arduino.org on twitter and on their forums, no reply yet and it seems their twitter account has been suspended. Should have bought a Genuino I guess.
