General Description
Top Side
The Honeywell HMR3100 is a low cost, two-axis
electronic compassing solution used to derive heading
output. Honeywell’s magnetoresistive sensors are
utilized to provide the reliability and accuracy of these
small, solid state compass designs. The HMR3100
communicates through binary data and ASCII
characters at four selectable baud rates of 2400, 4800,
9600, or 19200. This compass solution is easily
integrated into systems using a simple USART
interface.
