Product overview
The BWSENSING BW-IMU325E is an inertial measurement component for integration into unmanned aircraft, robots, autonomous vehicles and stabilized platforms. Its sensing architecture combines a gyroscope with an accelerometer measuring the X, Y and Z axes, with CAN providing the output interface. The unit specifies a 500Hz output frequency, temperature compensation from -40°C to +85°C, and compensation for nonlinearity and orthogonality. It is an integration component rather than a complete flight platform or airframe kit.
The packaged unit occupies 97 × 63 × 27.2mm, while the bare board measures 60 × 54 × 6mm; bare board length and width may vary by ±1mm. Electrical integration requires 9-36V DC, with 30mA operating current and a 40mA maximum. Measurement limits are ±400°/sec for the gyroscope and ±2g on each accelerometer axis. Bias stability figures depend on the stated averaging interval and temperature conditions. Protection specifications cover electrostatic discharge, electrical fast transients and surge immunity.
