In is a contactless magnetic position sensor for accurate angular measurement over a full turn of 360 degrees. To measure the angle, only a simple two-pole magnet, rotating over the center of the chip, is required. The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 0.0879º. This digital data is available as a serial bit stream.
The module can be fitted with circuit MMA8451Q. It is a 3-axis accelerometer with 14-bit resolution. A3G4250D circuit provides the 3-axis gyroscope. Both circuits enable communication via I2C. On the module is not necessary to assemble both IO.
