Motor Sheild V2
When the motor shield is stacked on an Arduino Uno, which digital and analog pin are available for use (that aren't used to communicate with the motor controller)?

Hi Hans,
The 4 motor channels are controlled via I2C using the SDA and SCL pins (A4 and A5 on an Arudino UNO). The i2C bus can be shared with other i2c devices - as long as they have unique i2c addresses.
The 2 servo ports are direct pass-through of digital pins 9 and 10. These are only used if you have servos connected. All other pins are unused by the shield and are available for other purposes.
