Product overview
The BWSENSING IMU300 is an inertial measurement unit for integration into unmanned aircraft, robots, autonomous vehicles and platform stabilization systems. Its sensing specifications cover gyroscope and accelerometer performance. The physical envelope measures 60 × 59 × 29 mm, with a separately specified mainboard size of 44 × 35 × 11 mm. These dimensions define the component’s integration space within a host system; the product is an inertial sensing unit rather than a flight platform or airframe kit.
Electrical integration uses a 9–36 V DC supply and a selectable RS232, RS485 or TTL output interface. Sampling reaches up to 500 Hz, while temperature, dynamic and orthogonality compensation are included features. The operating temperature range is -40°C to +85°C. Precision figures retain narrower measurement conditions: gyroscope bias stability is specified at room temperature over 100-second and 10-second intervals, while accelerometer bias stability is specified at 25°C over those intervals, with both sets expressed at 1σ.
