MU 6 Degrees of Freedom - v4 with Bluetooth Capability
Description: The 6DOF v4
Inertial Measurement Unit (IMU) is the latest Sparkfun IMU offering. The
v4 provides 3 axes of acceleration data, 3 axes of gyroscopic data, and
3 axes of magnetic data.Each independent channel is user selectable, as is the sampling frequency.The device can also report in ASCII or binary format, and can work over a wireless Bluetooth® link or a wired TTL serial connection.Control is provided through an LPC2138 ARM7 processor with plenty of extra memory for custom code development.All code is written using the free WinARM development platform.With our available source code, you can be doing your own development in minutes!
For a wireless link, the 6DOF will communicate with any Bluetooth® device
that supports the Serial-Port-Profile (SPP - most do!). However,
because of the dense amount of data across the serial link we recommend
the BlueDongle USB device below.
Having a hard time picking an IMU? Our Accelerometer, Gyro, and IMU Buying Guide might help!
Note: We've been encountering a lot
of noise on the x-axis magnetometer when using the 6DOF over Bluetooth.
If the output of this sensor is of vital importance, we really suggest
using the IMU over a hard-wired interface, which will drastically
diminsh the noise. Our engineers are aware of the issue and in the
process of resolving it. Please contact our tech support team
(techsupport at sparkfun dot com) if you have any questions.

Board stack comes fully assembled as shown. All sensors are internally
temperature compensated. All readings are available through any terminal
program in either ASCII, binary format, or with the improved 6DOF v4
IMU Mixer demo application (source code also available). Power is
supplied through a JST connector on the bottom board. See below for a
connector.
