* IMU weighs less than 1.5 grams
* .8" x .7" footprint
* Customizable FIR digital filter
* TTL UART communication interface
* 16-bit ADC resolution
* +/- 400 deg/s gyro dynamic range
* +/- 3 g accelerometer dynamic range
Sophisticated onboard filtering, simple user-interface
The CHR-6d Inertial Measurement Unit includes a customizeable Parks-McClellan windowed FIR filter to process sensor data. The filter is easily customized by sending commands over the TTL UART.
Open-source firmware makes the CHR-6d fully customizable
While the CHR-6d comes ready to use, it can also be reprogrammed for specialized applications. In addition to the UART, four extra GPIO pins are routed out for additional flexibility. At 64 Mhz, the onboard ARM Cortex™ processor is fast enough to handle a wide variety of sensing and control tasks.

), they also make mention of this :
CHR-9d Inertial Measurement Unit
Coming soon - the CHR-9 line incorporates rate gyro, accelerometer, and magnetometer data to create a self-contained attitude estimation system.
No news yet on pricing, but they said it should be available in Oct 2009.
