The CMPS11 module is a tilt compensated compass. Employing a 3-axis magnetometer and a 3-axis accelerometer and a powerful 16-bit processor, the CMPS11 has been designed to remove the errors caused by tilting of the PCB. Powered from 3.6-5V @35mA the compass outputs the bearing reading via serial, I2C or PWM interface.

The CMPS11 module is the 3rd generation tilt compensated compass from Devantech. Employing a 3-axis magnetometer and a 3-axis accelerometer and a powerful Kalman filter, the CMPS11 has been designed to remove the errors caused by tilting of the PCB.
The CMPS11 produces a result of 0-3599 representing 0-359.9 or 0 to 255. The output of the three sensors measuring x, y and z components of the magnetic field, together with the pitch and roll are used to calculate the bearing, each of these components are also made available in there raw form.
Examples of using the CMPS11 module with a wide range of popular controllers. The CMPS11 module requires a power supply at 3.6 - 5v and draws a nominal 35mA of current. There are three ways of getting the bearing from the module. A serial interface, an I2C interface or a PWM output.Interfaces
