Honeywell/Commercial Switch&Sensor's HMR3200/HMR3300 is an electronic compass solution module for navigation and guidance systems. It features a direction accuracy of 1˚, a resolution of 0.1˚, and a repeatability of 0.5˚. The HMR3300 has a ±60˚ tilt angle measurement range, operates in a temperature range of -40˚C to +85˚C, and supports single power supply of 6-15VDC. It can be used in applications such as orientation and navigation, attitude reference, satellite antenna positioning, platform leveling, GPS integrated systems, and laser range finders.
This manual describes the Honeywell HMR3200 and HMR3300 digital compass modules, including their physical dimensions, operating temperature range, and power requirements. It explains the magnetic field measurement capabilities, tilt angle range, and accuracy specifications for both models.
The document also details the communication interfaces (UART and SPI), pin assignments, command formats, and example commands for obtaining heading, pitch, roll, and magnetic field data. Ordering information for PCB demo kits and related accessories is provided at the end. This manual is written in Chinese.
