Product overview
The Wuxi Beiwei Sensing Technology IMU200 provides inertial measurement for applications including unmanned aircraft, robots and platform stabilization. Its physical integration dimensions distinguish the complete unit, measuring 60 × 59 × 29 mm, from its 44 × 35 × 11 mm mainboard. Electrical integration uses a 9–36 V DC supply, with selectable RS232, RS485 or TTL output. These options define the available interface choices for incorporating the sensor into a host system.
The IMU200 combines gyroscope and accelerometer measurement with temperature, dynamic and orthogonality compensation. Sampling reaches up to 500 Hz, and operation spans -40 to +85 °C. Its precision figures carry distinct measurement conditions: gyroscope bias stability is specified at room temperature, while accelerometer bias stability uses 25 °C and separate 10-second and 100-second intervals. Procurement scope is an inertial measurement component for integration into a larger system; the product is neither a flight platform nor an airframe kit.
