The Honeywell HMR3300 is a digital compass solution for use in precision heading applications. Honeywell's magnetoresistive sensor is utilized to provide the reliability and accuracy of these small, solid-state compass designs. This compass solution is designed for generic precision compass integration into customer systems using a 5-voltage logic level serial data interface with commands in ASCII format.
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. The HMR3300 is a highly-reliable, top-performance product that is delivered when promised. Honeywell's magnetic sensor provides real solutions you can count on.

* Null zeroing prior to use of the HMR3300 and upon exposure to temperature excursions beyond the Operating Temperature limits is required to achieve highest performance.
Physical Characteristics
The circuit board for the 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 HMR3300 is factory set with this switch fully clockwise, for selection of unregulated input (+6.5 to+15) voltage from the V+ pin (pin 8). By rotating the switch fully counterclockwise, 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.
