OpenMV IMU Expansion Shield

The OpenMV IMU Expansion Board not only captures acceleration, speed, and magnetic fields but also directly provides orientation, including quaternions and Euler angles.

OpenMV can capture the following sensor data:

• Absolute Orientation (Euler angles, 100Hz) - 3-axis orientation data 360°

• Absolute Orientation (Quaternions, 100Hz) - Quaternions represented as floating-point numbers for more precise operations.

• Angular Velocity (100Hz) - 3-axis rotational speed, unit is rad/s

• Acceleration (100Hz) - 3-axis acceleration (gravity + linear motion), unit is m/s^2

• Magnetic Field (20Hz) - 3-axis magnetic field, unit is micro Tesla (uT)

• Linear Acceleration (100Hz) - 3-axis linear acceleration (acceleration minus gravity), unit is m/s^2

• Gravity Acceleration (100Hz) - 3-axis gravity acceleration (minus all motion effects), unit is m/s^2

• Temperature (1Hz) - Ambient temperature, unit is Celsius
