ACEINNA OpenIMU335RI 6DOF Open-Source IMU Module

ACEINNA OpenIMU335RI 6DOF Open-Source IMU Module is a high-performance, rugged module with CAN and RS232 interfaces. The easy-to-use 6-DOF (9 optional) open inertial platform is packaged in a rugged sealed over-molded plastic housing. The ACEINNA OpenIMU335RI includes triple-redundant 3-Axis MEMS accelerometers and rate gyros which are fully calibrated over the operating temperature range.

The ACEINNA OpenIMU335RI 6DOF Open-Source IMU Module integrates a 168MHz ARM M4 CPU with a Floating Point Unit. The OpenIMU335RI runs the OpenIMU open-source stack that features an optimized 16-state Kalman Filter for Attitude and GPS-Aided Position Velocity-Time (PVT) measurement. The open navigation platform allows embedded navigation applications quickly developed on PC, MAC, and Ubuntu deployed to run on OpenIMU hardware.
