by Devantech Ltd (Robot Electronics)

Devantech CMPS03 compass module designed specifically for use in autonomous systems to aid in navigation. Heading information is available as a digital PWM signal as well as through an I2C interface.


Add To Cart


The compass must be mounted horizontally. Changing the tilt of the compass will affect the readings. The heading resolution is 0.1 degrees. The module is designed to operate at 100kHz I2C bus speeds, but is capable of operating at 400kHz and 1MHz when proper guidelines by Devantech are followed.
