Angle 10 Click is based on the AS5070A, a Hall-based rotary magnetic position sensor using a CMOS technology from ams AG. The lateral Hall sensor array converts the magnetic field component, perpendicular to the surface of the chip, into a voltage. The signals coming from internal Hall sensors are amplified and filtered before their conversion by the ADC and then processed by the CORDIC block to compute the angle and magnitude of the magnetic field vector. The intensity of the magnetic field is used by the automatic gain control (AGC) to adjust the amplification level to compensate for temperature and magnetic field variations.

The AS5070A provides a linear analog ratiometric output signal, which represents the angular orientation of the magnet above the AS5070A on a linear absolute scale, and is ratiometric up to 5V. The analog output voltage of the AS5070A is than sent directly to an analog pin of the mikroBUS™ socket labeled as AN.

A unique addition to this board is a position for a Rotary Magnet Holder designed to be used alongside a magnetic rotary position sensor allowing fast prototyping and quick measurements during development.

This Click board™ can be operated only with a 5V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
