Compass Sensor Module The OSEPP Compass Sensor Module is a 3-axis digital compass for low-field magnetic sensing. It utilizes the Honeywell HMC5883L state-of-the-art high resolution magneto-resistive sensors, an ASIC containing amplification, automatic degaussing strap drivers, offset cancellation, and a 12-bit ADC that enables a compass heading accuracy to within 1-2 degrees. The module uses the I²C interface for data communication. The I²C lines are packaged with the power and ground lines into a modular connector, which allows easy plug and play operation. There are two connectors on the module to enable daisy chaining of multiple I²C devices together. The Compass Sensor Module is ideal for applications that require the measurement of both the direction and the magnitude of Earth’s magnetic field, from milligauss to 8 gauss. Features Plug and play with OSEPP I²C Expansion Shield 12-Bit ADC with 2 milligauss field resolution in +/- 8 gauss field to enable 1-2 degree compass heading accuracy Fast 160 Hz maximum output rate Low power consumption Supports I²C interfacing with 7-bit address of 0x1E Provides pass-through connector to support daisy chaining of multiple sensors from the OSEPP Sensor Module family Provides 0.1” breakout points for power and I²C interface pins access
