The Atomic IMU 6 Degrees of Freedom - XBee Ready is designed to give good performance at a low price. The unit can run as a hard-wired UART interface (0-3.3V, 115200bps), or with an XBee RF module. The processor is an Atmel ATMega328 running at 10MHz with 6 dedicated 10-bit ADC channels reading the sensors. It uses a Freescale MMA7361L triple-axis accelerometer, which is configurable to 1.5 or 6g sensitivity. Riding along with the MMA7361L are three ST Microelectronics LISY300AL single-axis, 300°/s gyros. Source code for the 6DOF Atomic is freely available and compiles with the free AVR GCC compiler. It also internally temperature compensated. The 6DOF Atomic does not have any filtering in firmware, though there is enough memory left in the ATMega168 flash program space to implement filtering. The internally set output bandwidth for the LISY300AL gyro sensors is 88Hz.
Note: The datasheet for this product is outdated by a few revisions. The interface is essentially the same though, the only change has been the replacement of the Accelerometer IC resulting in the ability to choose only between 1.5g and 6g sensitivity.
