As of Oct 1, 2014 we are now shipping this board with the next generation L3GD20H chip rather than the L3GD20. Its nearly 100% code-compatible (the ID register has changed) and has better noise rate density (0.011 dps/Hz vs 0.03 dps/Hz).
A gyroscope is a type of sensor that can sense twisting and turning motions. Often paired with an accelerometer, you can use these to do 3D motion capture and inertial measurement (that is – you can tell how an object is moving!) As these sensors become more popular and easier to manufacture, the prices for them have dropped to the point where you can easily afford a triple-axis gyro! Only a decade ago, this space-tech sensor would have been hundreds of dollars.
Since this chip is a 3.3V max device, but many of our customers want to use it with an Arduino, we soldered it to a breakout board with level shifting circuitry so you can use the I2C or SPI interface safely using a 5V interface device. We also place a 3.3V regulator on there so you can power it from 5V.
Since we expect people will want to attach it firmly to their project, the PCB comes with four 2.1mm mounting holes. Use #2-56 imperial or M2 screws screws.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
