CM1020 ELECTRONIC COMPASS MODULE COMPLETE DIRECTION DETECTION MODULE WITH UNAGI NETLLC MAGNETOMETER AND ACCELEROMETER General Description The CM1020 is a complete electronic compass module, that outputs accurate directional data without the need for manual calibration or additional components. Utilizing a 3 axis magnetometer along with a highly sensitive triaxial accelerometer, the CM1020 calculates Features its position relative to terrestrial magnetism, and outputs its direction in degrees. Gyroscopic output Completely tested self-contained module data is also available. No additional circuits or components required Patented Auto-Calibration With its built-in microprocessor core, the CM1020 No special equipment or methods required to automatically calibrates itself using patented calibrate for accurate direction detection algorithms, so that the module is always ready to operate correctly. Simply apply DC power to the Highly accurate direction detection module, and then read the appropriate registers to find Direction values from 0.0 to 359.9 degrees its direction. The module does all the detection and Includes Gyro data: Inclination, Pitch, Roll, Yaw heavy calculations. Low-power consumption Ideal for battery operation The CM1020 communicates via a simple serial communication port. The CM1020 only requires a Easy to interface single 3.3VDC power supply and is very low in power Single DC supply and a simple serial interface. consumption (< 350mW). Compact size 1.0 x 1.5 x 0.13 The CM1020 module is very small in size, 1.0 x 1.5 x Ideal for hand-held or other portable products 0.13. This allows the module to be easily incorporated into handheld or other portable devices. Applications The module contains a single 12-pin header which Automobile navigators contains all the power and interface signals. Portable GPS mapping equipment The CM1020 module is built with high-volume Weather station loggers manufacturing techniques, to keep quality high and Construction equipment costs low. Each module is 100% tested with accuracy Marine mapping displays guaranteed.
