New! HMC5843 Three-Axis
Compass IC |
The HMC5843 3-Axis Electronic Compass improves accuracy of location readings in mobile
phones, personal navigation devices, portable auto navigation systems and game
controllers. Featuring I2C serial bus interface for high volume
applications, this new 3-axis compass IC will increase functionality in
consumer electronics by providing expanded direction awareness when
overlaid on
GPS enabled maps, utilizing magnetic sensors to add
compassing, pointing and
heading. The HMC5843 offers a precision
3-axis magnetic sensor trio coupled to
a 12-bit ADC with an I2C
output in a miniature surface mount package.
The
product
description, features, package, pinout, and spec sheet can be
found on
the DATASHEET
(PDF).
 Evaluation board for the Compass IC contains the HMC5843 atop a 0.8" by
0.8" plug-board with wide-DIP spaced (0.6") pins for solderless breadboard
compatibility. The evaluation board also contains the two capacitors and I2C
pull-up resistors needed for typical function for the retrieval of the XYZ
magnetic field information. Both single and dual supply configurations of the
HMC5843 are supported.
 Demonstration board for the 3-axis Compass IC provides the HMC5843 plus serial
bus conversion circuits to convert the I2C data to USB interfacing for personal
computers. Includes a 6-foot USB cable, software, user manual & 5 samples of
the HMC5843.

HMC6343 Three-Axis
Compass with Algorithms |
The HMC6343 digital
compass circuit is three-axis magnetic and three-axis accelerometer compassing
solution with tilt compensation. This 9.0mm by 9.0mm by 1.9mm multi-chip module
with a UART interface plus command compatibility with the HMR3300/3400 compass
solutions. The HMC6343 contains all sensors, microcontroller, and analog
support circuits; plus all the firmware for heading computation and hard-iron
calibration. The
product description, features, package, pin out, and spec
sheet
can be found on the DATASHEET
(PDF).
Evaluation board for the
tilt-compensated digital compass IC contains the HMC6343 mounted on the
0.8" by 0.8" plug-board with wide-DIP spaced (0.6") pins for
solderless breadboard compatibility. The board also contains the external
capacitor and I2C pull-up resistors for typical function of the compass. The
board contains the four connections (VDD, GND, SCL, SDA) plus other breakouts.
Demonstration board provides the HMC6343
part plus serial bus conversion circuits to convert the I2C data to USB
interfacing to personal computers. This small printed circuit board comes with
a 6-foot USB cable and Windows demonstration software to provide a user
friendly way of viewing compass heading, pitch and roll data numerically and on
aviation-type displays. Communication can still
be enabled with the HMC6343,
even without the provided
demonstration software, as long as the developer
creates a
program to emulate the I2C data packets. This demonstration
board uses the USB power supply from the host computer (~+5
volts) and a green LED
indicates power presence.

HMR3300
Digital Three-Axis Tilt Compensated Compass |
 The
HMR3300 is a three-axis, tilt compensated compass that uses a two-axis
accelerometer for enhanced performance up to a 60° tilt range. Heading accuracy
is 1 degree with 0.1 degree resolution and 0.5 degree repeatability. Tilt range
(Pitch and Roll) is �60�. Compensation for Hard Iron Distortions, Ferrous
Objects, and Stray Fields. The product description, features, package, pin out, and
specs can be found on the DATASHEET
(pdf).

HMR3500
TruePoint™ Compass Module |
The HMR3500 TruePoint™ electronic compass is a 3 axis digital
compass module that can be mounted and used in any orientation. Azimuth
accuracy is 1 degree with 0.1 degree resolution and 0.5 degree repeatability. The product
description, features, package, and specs can be found on the DATASHEET
(pdf).

DRMŽ4000
Dead Reckoning Module |
 The DRMŽ4000 Dead Reckoning Module provides accurate position information
for first responders and other people on foot in places that the global
positioning system (GPS) is unable to reach. The small, easy-to-integrate unit
contains ten sensors including three gyros, accelerometers and magnetometers as
well a barometric altimeter to accurately deliver position location. The
DRMŽ4000 uses patented motion classification algorithms to analyze walking
motion and compensate for unique user kinematics. The DRMŽ4000
contains an
internal Kalman filter for integrating onboard
sensors and external GPS data.
It nominally provides position
data that is accurate to within 2% of the actual
distance
traveled by a user in environments without GPS. The unit
can be
directly interfaced to many GPS receivers and
man-pack computers and includes
capabilities for accurate
field calibration. The product description, features,
package,
and specs can be found on the DATASHEET
(pdf).
