L3GD20 3-Axis Gyro Carrier with Voltage Regulator
This sensor is a carrier/breakout board for the ST L3GD20 three-axis gyroscope, which measures the angular rates of rotation about the roll (X), pitch (Y), and yaw (Z) axes. Angular velocity measurements with a configurable range of ±250°/s, ±500°/s, or ±2000°/s can be read through a digital I²C or SPI interface. The board has a 3.3 V linear regulator and integrated level-shifters that allow it to work over an input voltage range of 2.5–5.5 V, and the 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.
Clearance: This board is being replaced by the newer L3GD20H carrier and LSM6DS33 carrier.

L3G Arduino library
This is a library for the Arduino that interfaces with our L3GD20H and L3GD20 3-axis gyro carriers as well as the gyros on the MinIMU-9 v3 and AltIMU-10 v3 (it also works with older versions of those boards, some of which used the L3G4200D and the L3GD20). It makes it simple to configure the device and read the raw gyro data.

Using the L3GD20 gyroscope in control systems
This is a YouTube playlist by control systems lecturer Brian Douglas that uses the L3GD20 MEMS gyroscope. It describes the fundamentals of the gyro and how to use it for closed and open loop control projects with MATLAB/Simulink and Arduino.
