Digital Compass Solutions
HMR3200/HMR3300
The Honeywell HMR3200/HMR3300 are digital compass
solutions for use in precision heading applications.
Honeywell’s magnetoresistive sensors are utilized to
provide the reliability and accuracy of these small, solid
state compass designs. These compass solutions are
designed for generic precision compass integration into
customer systems using a 5-voltage logic level serial data
interface with commands in ASCII format.
The HMR3200 is a two-axis precision compass with three
orthogonal magnetoresistive sensors, and can be used in
either vertical or horizontal orientations.
The HMR3300 includes a MEMS accelerometer for a horizontal three-axis, tilt compensated precision compass for
performance up to a ±60° tilt range.
Honeywell continues to maintain product excellence and performance by introducing innovative solid-state magnetic
sensor solutions. These are highly reliable, top performance products that are delivered when promised. Honeywell’s
magnetic sensor solutions provide real solutions you can count on.

PHYSICAL CHARACTERISTICS
The circuit board for the HMR3200/HMR3300 Digital Compassing Solutions is approximately 1.45 by 1 inches. An 8-Pin
header protrudes down on the rear edge of the compass circuit board for the user electrical interface to the motherboard.
The header pins extend 5/16” below the board plane with the bottom-side mounted magnetic sensor integrated circuits
(HMC1021Z and HMC1022) extending 3/16” below the board plane. Components on the top-side have a maximum height
of 1/8”.
In addition two single pins, identical to the 8 header pins, are placed on the sides toward the forward edge of the circuit
board (HMC1021Z is at the magnetic front or north reference). These single pins are for mechanical mounting and do not
have electrical connections to the compass electronics.
POWER SUPPLY INTERFACE
Rotary switch (SW1) is located near pins 6 and 7, and is used to select the customer provided power supply voltage type.
The HMR3200/3300 is factory set with this switch fully clockwise, for selection of unregulated input (+6 to+15) voltage
from the V+ pin (pin 8). By rotating the switch fully counter-clockwise, users may provide a regulated +5 volt supply to the
+5 pin (pin 6) as an alternative. Incorrect switch settings may cause no response or faulty responses. Upon correct power
application, light emitting diode D2 turns on for about one second afterwards to indicate the execution of the initialization
firmware. Do not use both power inputs simultaneously.
Figure 1 shows a typical HMR3200/HMR3300 circuit board assembly with the basic dimensions.
MOUNTING CONSIDERATIONS
The HMR3200/HMR3300 precision compasses use the ten integrated circuit style pins to plug into compatible
motherboards for electrical interface, and to be orientated mechanically. The pins are nominally 0.030” in diameter and
0.200 in length. Trimming the pin lengths or removing the pins voids the warranty, as Honeywell can not retest the
modified compasses (socketized test fixtures). Wires can be substituted for the pins, but caution should be used in
soldering to not damage the pin solder pads.
The HMC1021Z part is an 8-pin SIP device that is shipped carefully in a nearly perfectly vertical orientation with respect to
the horizontal referenced circuit board. Do not bend or reposition this part, or the factory magnetic calibration will be no
longer valid. Should the part be accidentally bent, return for recalibration is possible or align the part vertical to recapture
most of the accuracy. Correct flat orientation of the compass modules is with the pins pointing downward.
CIRCUIT DESCRIPTION
The HMR3200/HMR3300 Digital Compass Solutions include all the basic sensors and electronics to provide a digital
indication of heading. The HMR3200 has all three axis of magnetic sensors on board, but allows the user to select which
