Product overview
The Wuxi Beiwei Sensing Technology BW-VG55 measures dynamic and static inclination for integration into UAVs, robots, platform stabilization systems and other machinery. Its sensing functions include nonlinearity and orthogonality compensation, gyroscope drift compensation, a special bias-tracking algorithm and Kalman filtering. Pitch measurement spans ±90°, while roll spans ±180°. The distinction between its 3° dynamic accuracy and 0.3° static accuracy matters when selecting it for moving equipment; its 0.01° resolution is a separate specification.
The physical configurations comprise a packaged sensor measuring 55 × 37 × 24 mm and a bare board measuring 33 × 27 × 6 mm. Bare-board length and width may vary by ±1 mm, so integration space must accommodate the actual unit. Electrical integration requires 5–12V DC, with 30mA operating current and a 40mA maximum. The CAN interface, specified serial rates of 2400–115200 baud and high-performance binary output protocol define communication considerations. Startup delay is below 50ms, and maximum output frequency is 100Hz.
