The Acc_Gyro(6 DOF) is a 6 degrees of freedom Inertial Measurement Unit (IMU), capable of measuring acceleration on all 3-axis as well as rotation rate about the X, Y and Z axis. Combining values from both accelerometer and gyroscope will allow you to obtain accurate values of inclination angles relative to the earth's surface (see Starlino's IMU guide).
Key Features and Components:
– LIS331AL (datasheet) – analog 3-axis 2G accelerometer
– LPR550AL (datasheet) – a dual-axis (Pitch and Roll), 500deg/second gyroscope
– LY550ALH (datasheet) – a single axis (Yaw) gyroscope
– Built-in 3.3V regulator, board can be used in both 3.3V and 5V projects
– Built-in analog high-pass and low-pass filters, for noise rejection and drift compensation
Dimensions: 1.8" x 0.8" (46 x 21 mm)
Supply current: < 10mA
Supply voltage: 3.3V to 6V

Hello Sir/Ma’am,
I am a member of Formula Student Racing Team and we require an inertial measurement unit for measuring our car’s acceleration and angular velocities. Can you provide me with the quote and lead time of the ACC_GYRO 6DOF ANALOG IMU.
Thank you.
