Product overview
Wuxi Beiwei Sensing Technology’s IMU300 is an inertial measurement unit incorporating gyroscope and accelerometer functions for applications including unmanned aircraft, robotics and platform stabilization. Its external dimensions are 60 × 59 × 29 mm, with a separately specified mainboard measuring 44 × 35 × 11 mm. These dimensions define the component’s integration space. The electrical configuration offers selectable RS232, RS485 or TTL output, a 9–36 V DC supply range and sampling at up to 500 Hz.
The IMU300 supports operation from −40°C to +85°C and includes temperature, dynamic and orthogonality compensation. Its gyroscope specifications cover bias stability, angular random walk, bias repeatability and scale factor nonlinearity; accelerometer specifications cover resolution, bias and bias stability. Measurement conditions matter: gyroscope bias stability is specified at room temperature for 100-second and 10-second intervals, while accelerometer bias stability uses those intervals at 25°C. The product is an inertial sensing component for integration into a larger system.
