U4930-B Six-Axis MEMS Inertial Measurement Unit
MEMS IMU · U4930-B
A six-axis inertial module combining three gyroscope axes with three accelerometer axes for attitude and motion measurement. Designed for integration into navigation and control systems where high-rate output and a wide operating temperature range are important.
- Gyroscope range: ±400 °/s
- Accelerometer range: ±30 g
- Maximum data rate: 2,000 Hz
- Operating temperature: −40 to +80 °C
For HG4930 replacement projects, confirm connector, mounting, protocol and performance against your system requirements.
Product overview
The U4930-B provides angular-rate and linear-acceleration data from one compact MEMS assembly. Its internal compensation addresses bias, scale factor and axis-related errors across temperature. Hardware and software configuration should be reviewed for each integration project.

FAQ
What does the U4930-B measure?
It measures angular rate on three axes and linear acceleration on three axes.
Can it replace an HG4930?
The source positions the U4930 series for HG4930 replacement projects. Confirm mechanical fit, pinout, power, timing, data format and measured performance in the target system before selection.
What interface is described?
The source FAQ describes RS422 communication, a default 200 Hz output rate and a default 460800 bps baud rate. Ask for the current U4930-B interface document before integration.
