MinIMU-9 v5 Gyro. Accelerometer. and Compass [LSM6DS33 and LIS3MDL Carrier] (Pololu Robotics and Electronics)
The Pololu MinIMU-9 v5 is a compact (0.8 ? 0.5) board that combines ST's LSM6DS33 3-axis gyroscope and 3-axis accelerometer and LIS3MDL 3-axis magnetometer to form an inertial measurement unit (IMU); we therefore recommend careful reading of the LSM6DS33 datasheet (1MB pdf) and LIS3MDL datasheet (2MB pdf) before using this product. These sensors are great ICs, but their small packages make them difficult for the typical student or hobbyist to use. They also operate at voltages below 3.6 V, which can make interfacing difficult for microcontrollers operating at 5 V. The MinIMU-9 v5 addresses these issues by incorporating additional electronics, including a voltage regulator and a level-shifting circuit, while keeping the overall size as compact as possible. The board ships fully populated with its SMD components, including the LSM6DS33 and LIS3MDL, as shown in the product picture.
