OpenIMU Development Platform

Link to OpenIMU



OpenIMU300RI is a rugged, sealed-package, open-source, nine-degree-of-freedom (9-DOF) inertial measurement unit (IMU) for off road, construction, agricultural and automotive applications. The OpenIMU300RI features a precision 3-Axis Accelerometer, low-drift 3-Axis Rate Gyro, and 3-Axis Magnetometer and 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.
