Code & Deploy

Customize and deploy algorithms directly on ACEINNA’s OpenIMU hardware using Free VS Code Extension. Implement an INS Kalman Filter.


Connect ACEINNA OpenIMU directly to ACEINNA Navigation Studio to record and analyze real-world results.

OpenIMU Development Platform

Link to OpenIMU



The ACEINNA OpenIMU300ZI is an easy-to-use high-performance 9 DOF open source 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.
