This Module is a digital triple-axis magnetometer. The MAG3110 sensor features an ASIC in charge of control and I2C communications in addition to a magnetic transducer that can measure magnetic fields (full-scale up to around 1000uT). A 3-axis accelerometer may be used in conjunction with the MAG3110 to build an orientation-independent electronic compass that can deliver precise heading data. It communicates via a two-wire I2C interface with data output rates of up to 80 Hz in fast mode (up to 400 kHz). From 1.95V to 3.6V can be used to power the board. The pins are 0.1′′ (2.54mm) apart to make breadboarding simple. The I2C lines include two solder jumpers, four mounting holes, and pull-up resistors to choose from.
