OpenIMU300 EZ-Family High-Performance IMU The ACEINNA OpenIMU300E is an easy-to-use high-performance 9-DOF open inertial platform. The OpenIMU300 features a precision 3-Axis Accelerometer, low-drift 3-Axis Rate Gyro, and 3-Axis Magnetometer. The low-power platform is powered by a 168MHz ARM M4 CPU with a Floating Point Unit. The OpenIMU300 runs the OpenIMU open-source stack that includes an optimized full-state Kalman Filter for Attitude and GPS-Aided Position- Velocity-Time (PVT) measurement. A free tool-chain based on VS Code supports PC, MAC, Ubuntu.
