Dieses Board ist eine inertiale Messeinheit mit 9 Freiheitsgraden (9DoF-IMU) zur
zuverlässigen Messung der Drehrate und Beschleunigung in allen drei
Zusätzlich besitzt das Board einen 3-Achsen Magnetfeld Sensor.
Vollständige Beschreibung in Englisch:
The 9DOF Razor IMU incorporates three sensors - an ITG-3200
(triple-axis gyro), ADXL345
(triple-axis accelerometer), and HMC5883L
(triple-axis magnetometer) - to give you nine degrees of inertial
measurement. The outputs of all sensors are processed by an on-board
ATmega328 and output over a serial interface. This enables the 9DOF
Razor to be used as a very powerful control mechanism for UAVs,
autonomous vehicles and image stabilization systems.
The board comes programmed with the 8MHz Arduino bootloader (stk500v1) and some example firmware
that demos the outputs of all the sensors. Simply connect to the serial
TX and RX pins with a 3.3V FTDI Basic Breakout, open a terminal program
to 57600bps and a menu will guide you through testing the sensors. You
can use the Arduino IDE to program your code onto the 9DOF, just select
the 'Arduino Pro or Pro Mini (3.3v, 8mhz) w/ATmega328' as your board.
The 9DOF operates at 3.3VDC; any power supplied to the white JST
connector will be regulated down to this operating voltage - our LiPo
batteries are an excellent power supply choice. The output header is
designed to mate with our 3.3V FTDI Basic Breakout board, so you can
easily connect the board to a computer's USB port. Or, for a wireless
solution, it can be connected to the Bluetooth Mate
or an XBee Explorer
