Digital Compass Solutions HMR3200/HMR3300 The Honeywell HM R3200/HMR3300 a re di gital compass solutions for use in p recision hea ding appli cations. Honeywell’s magn etoresistive sensors a re util ized to provide the reliability and accu racy of these small, solid state com pass d esigns. These compass soluti ons a re designed for gene ric p recision comp ass integ ration into customer systems usi ng a 5-voltage logic level se rial data interface with commands in ASCII format. The HMR3200 is a two-ax is p recision compass with three orthogonal m agnetoresistive se nsors, and can b e used in either vertical or horizontal orientations. The HMR33 00 in cludes a MEMS accele rometer f or a h orizontal three -axis, tilt compen sated preci sion com pass f or performance up to a ±60° tilt range. Honeywell continue s to maintain pro duct excell ence and p erformance by introdu cing in novative soli d-state ma gnetic sensor soluti ons. These are highly reli able, top performance products that are delivered when pr omised. Honeywell’s magnetic sensor solutions provide real solutions you can count on.

An 8 -Pin header protrudes down on the rear edge of the compass circuit board for the user electrical interface to the motherboard. The h eader pins extend 5/16” below the bo ard pla ne with th e b ottom-side mounted magnetic sen sor in tegrated 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 singl e pins, identical to the 8 hea der pins, are placed on the si des toward th e forward e dge 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 fa ctory set with this switch fu lly clockw ise, for selection of un regulated inp ut (+6 to+15) voltag e 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 abo ut one second a fterwards to indicate the e xecution of the initialization firmware. Do not use both power inputs simultaneously. Figure 1 shows a typical HMR3200/HMR3300 circuit board assembly with the basic dimension.
