HMR3400, Digital Compass Solution

Power and Signal Ground UART Receive Data/SPI Data Output UART Transmit Data/SPI Data Input +5 VDC Regulated Power Input www.honeywell.com HMR3400 BASIC DEVICE OPERATION The HMR3400 Digital Compass Solution includes all the basic sensors and electronics to provide a digital indication of heading.

Digital Compass Solution HMR3400 The Honeywell HMR3400 is a digital compass solution designed for use in navigation and precision pointing applications.

Honeywell’s magnetoresistive sensor technology is coupled with a MEMS accelerometer to provide a miniature, reliable tilt-compensated electronic compass.

Using a common set of commands from the legacy HMR3300 digital compass solution, the HMR3400 is designed to be easily integrated into host systems with a regulated 5 volt supply and a UART seri
