This breakout board is based on ST L3GD20H three-axis gyroscope, which measures the angular rates of rotation about the roll (X), pitch (Y), and yaw (Z) axes. Angular velocity measurements can be read through a digital I2C or SPI interface.
In the file "I2C-Explore-Labs-3D-Gyroscope-L3GD20H-Breakout-Board.ino" the use of the function Wire.requestFrom() can be improved.
