CHR-6d IMU

Produktbeschreibung

The CHR-6d is a 6-axis IMU, combining three accelerometer axes and three rate gyro axes in a .8" by .7" footprint. An onboard ARM Cortex™ processor samples and filters gyro and accelerometer outputs and sends results over a TTL (3.3V) UART. The CHR-6d was designed specifically for low cost and ease of use.

Data Outputs

• 3-axis roll rates (+/- 400 deg/s)
• 3-axis acceleration (+/- 3 g)
• Pitch and roll angles
• 16-bit effective measurement resolution (after oversampling and decimation)

Features

• Configurable digital filter (windowed Parks-McClellan FIR)
• Onboard EKF for pitch and roll angle estimation
• Automatic bias calibration
• High bias stability over temperature
• Adjustable output rates (20 Hz - 300 Hz)
• Easy to use TTL (3.3V) UART interface
• Open-source firmware with free development tools
• Open-source PC software for data visualization and IMU configuration
• Optional Development Kit

Convenient PC Interface for Configuration

The CHR-6d can be configured by sending commands over the TTL UART. To simplify this process, our open-source PC software provides a convenient interface for data visualization and IMU configuration.
