CMPS12 - Tilt Compensated Compass Module

The CMPS12 is the 4th generation tilt compensated compass from Devantech. Employing Bosch BNO055 featuring a 3-axis magnetometer, 3-axis gyro and a 3-axis accelerometer and a powerful 16-bit microprocessor.

The CMPS12 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 three raw form.

The CMPS12 module requires a power supply at 3.6 - 5V and draws a nominal 18mA of current. The signal level is 3.3V, but is 5V tolerant. A choice of serial or I2C interfaces are provided.

Features:

• Power - 3.3V-5V 18mA Typ.
• Resolution - 0.1 Degree
• Accuracy - Better than 1%. after calibration
• Signal levels - 3.3V, 5V tolerant
