The CMPS10 module is a tilt compensated compass. Employing a 3-axis magnetometer and a 3-axis accelerometer and a powerful 16-bit processor, the CMPS10 has been designed to remove the errors caused by tilting of the PCB. Powered from 3.3-5V @25mA the compass outputs the bearing reading via serial, I2C or PWM interface.

The CMPS10 module is a tilt
compensated compass. Employing a 3-axis magnetometer and a 3-axis accelerometer
and a powerful 16-bit processor, the CMPS10 has been designed to remove the
errors caused by tilting of the PCB.

The CMPS10 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 CMPS10 module with a wide range of popular controllers. The CMPS10
module requires a power supply at 3.3 - 5v and draws a nominal 25mA of
current. There are three ways of getting the bearing from the module. A serial
interface, an I2C interface or a PWM output.Interfaces
