Thanks to its combination of open-source software and low-cost hardware, the OpenIMU enables advanced, easy-to-deploy localization and navigation algorithm solutions for drones, robotics, and autonomous applications, at a fraction of the time and cost of traditional methods, claims the company.

The freely downloadable software stack at includes a FreeRTOS-based data collection and sampling engine, a performance-tuned, real-time, navigation-grade GPS/INS Kalman Filter library, a free IDE/compiler tool chain based on Visual Studio Code, JTAG debugging for debugging the code loaded on the IMU, data logging, graphing, Allen Variance plots, and maps, extensive documentation and a robust simulation environment with advanced sensor error models. Several ready to install free GPS/INS and IMU applications are available on Aceinna’s Navigation app store too.

The OpenIMU Development hardware development kit includes JTAG-pod, precision mount fixture, EVB, and an OpenIMU300 module. The OpenIMU module features Aceinna’s 5 deg/Hr, 9-Axis gyro, accelerometer, and magnetometer sensor suite with an onboard 180MHz ARM Cortex floating-point CPU. 

The IMU is delivered in a 24x37x9.5mm, easy to integrate module that operates from 2.7 to 5.5VDC.
