OpenIMU330B
Triple-redundant 6-DOF surface mount IMU that runs the OpenIMU open source navigation stack.
- Triple-redundant 6-DOF
- 1.5 deg/hr gyro bias
- SPI / UART
- 11 x 15 x 3.4 mm BGA
Overview
The OpenIMU330B is a small surface mount 6-DOF inertial measurement unit with triple-redundant 3-axis accelerometers and 3-axis rate gyros. It runs on a 32-bit ARM M4 CPU with floating point unit and uses Aceinna's OpenIMU open source stack, which includes a 16-state extended Kalman filter for attitude and GPS-aided position, velocity and time. Aceinna designed it for automotive Level 3 ADAS and other high-volume applications.
Built for
- Autonomous vehicles
- Self-driving taxis and delivery vehicles
- ADAS systems
- Electronic stability control and lane keep assist
Key features
Triple-redundant sensors
Three sets of 3-axis MEMS gyros and accelerometers support fault-tolerant designs.
Open source algorithms
Runs the OpenIMU stack with a built-in 16-state extended Kalman filter.
ARM M4 processor
A 32-bit ARM M4 CPU with floating point unit runs custom algorithms on the module.
Ready-to-use outputs
