The module includes a state-of-the-art, high-resolution QMC5883X series magneto-resistive sensor, plus an ASIC containing amplification, automatic degaussing strap drivers, offset cancellation, and a 12-bit ADC that enables 1° to 2° compass heading accuracy. The I2C serial bus allows for easy interface.
Features:
- The Honeywell QMC5883L is a surface-mount, multi-chip module designed for low-field magnetic sensing with a digital interface for applications such as low cost compassing and magnetometry
- The 12-Bit ADC coupled with low noise AMR sensors achieves 5 milli-gauss field resolution in ±8 gauss fields
- Low voltage operations and low power consumption; supports built-in self-test
- Built-in strap drive circuits, I2C digital interface, wide magnetic field range (+/-8 oe)
- Working voltage: 3.3V - 5V
- PCB size: 1.3 x 2.3 cm (QMC5883L size: 3.0 x 3.0 x 0.9 mm), with a 16-pin leadless chip carrier (LCC)
