OSEPP Compass Sensor Module - COMP-01

OSEPP Compass Sensor Module - COMP-01

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 OSEPP 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.
