The CMPS01 Magnetic Compass Module has been specifically designed as a robot navigation aid.

This module can easily be connected to many popular microcontroller's via the I2C bus.

The compass uses two Philips KMZ10A magnetic field sensors that are sensitive enough to detect the Earths magnetic field. The module generates a number that indicates the bearing of the robot in relation to the local magnetic field. This number can then be read by the microcontroller.

Specifications:

• Voltage: 5V only
• Current: 20mA typical
• Resolution: 0.1 degree
• Accuracy: 3-4 degrees approx. after calibration
• Output 1: Timing pulse 1mS to 37mS in 0.1mS increments
• Output 2: I2C interface, 0-255 and 0-359.9 SCL speed up to 1MHz
• Small size:32mm x 35mm
