Crowtail-3-Axis Compass module, a member of Crowtail family uses I²C based Honeywell HMC5883L digital compass. This ASIC is equipped with high resolution HMC118X magneto-resistive sensors and a 12-bit ADC. It provides compass heading accuracy up to 1° to 2°. Signal conditioning like amplification, automatic degaussing strap drivers and offset cancellation are inbuilt. This Crowtail module also includes a XC6206P332MR for power supply requirement. Hence user can connect any 3.3V to 6V DC power supply.
