Atomic IMU 6 Degrees of Freedom - XBee Ready

sku: SEN-09184

Description: The 6DOF Atomic is a stripped-down IMU, designed to give good performance at a low price. The unit can run as a hard-wired UART interface (0-3.3V, 115200bps), or optionally with an XBee  RF module, and is powered from a single LiPo (Lithium Polymer) battery. The processor is an Atmel ATMega168 running at 10MHz with 6 dedicated 10-bit ADC channels reading the sensors. Source code for the 6DOF Atomic is freely available and compiles with the free AVR GCC compiler.

The 6-DOF Atomic uses these sensors:

• 1 x Freescale MMA7260Q TM triple-axis accelerometer, settable to 1.5g, 2g, 4g or 6g sensitivity
• 3 x ST Microelectronics LISY300AL TM single-axis, 300/s gyros

All sensor readings are available through any terminal program in either ASCII or binary format, or with the 6DOF Atomic IMU Mixer demo application (source code also available).

Specifications:

• Input voltage: 3.4V to 10V DC
• Current consumption: 24mA (75mA with X-bee)
• Sensor bandwidth and resolution:
