The CMPS09 module is a tilt compensated compass. Employing a 3-axis magnetometer and a 3-axis accelerometer and a powerful 16-bit processor, the CMPS09 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. ** See the new CMPS10 Compass **

The CMPS09 module is a tilt compensated compass. Employing a 3-axis magnetometer and a 3-axis accelerometer and a powerful 16-bit processor, the CMPS09 has been designed to remove the errors caused by tilting of the PCB. The CMPS09 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. Devantech have also written examples of using the CMPS09 module with a wide range of popular controllers. The CMPS09 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.
Voltage - 3.3v-5v only required
Current - 25mA Typ.
Resolution - 0.1 Degree
Accuracy - Horizontal, 3-4 degrees.
Accuracy - Tilted to +/- 60 degrees, 4-5 degrees
Output 1 - I2C Interface, SMBUS compatible, 0-255 and 0-3599 , 100khz
Output 2 - Serial port, 9600 baud, no parity, 2 stop bits and 3.3v-5v signal levels
Output 3 - Timing Pulse 1mS to 37mS in 0.1mS increments
Small Size - 24mm x 18mm
