How Does The Magneto 14 Click Board™ Work?
The Magneto 14 Click Board™ is based on the MA735, a contactless angle sensor with ABZ and PWM output from Monolithic Power Systems. It can detect an absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder on a rotating shaft. The adjustable digital filtering can optimize control loop performance when used in servo applications. In addition, the sensor features magnetic field strength detection with a programmable threshold and on-chip non-volatile memory. This memory can store configuration parameters, including magnetic field detection thresholds, ABZ encoder settings, and reference zero-angle positions. The frequency of the PWM output of the sensor is up to 1090Hz with a 14-bit resolution.

The MA735 uses integrated Hall devices to detect the magnetic field, while the angle is measured using MPS's proprietary Spinaxis™ method. This method is based on phase detection and digitizes the direction of the field directly, generating a sinusoidal signal with a phase that represents the angle of the field. The angle is obtained from a signal by a time-to-digital converter, and the digital number proportional to the magnetic field is delivered at a rate of 1MHz.
Two headers on this Click board™ allow additional functionalities. The SSI header with SSD and SCK pins is a 2-Wire synchronous serial interface for data reading only and can be used for angle reading operation. The INC OUT header is an incremental output encoder with A, B, and Z pins. The ABZ encoder emulates a 12-bit incremental encoder (like an optical encoder), providing logic pulses per turn from 1 to 1024 in quadrature.
A unique addition to this board is a position for a Rotary Magnet Holder designed to be used alongside a magnetic contactless angle sensor allowing fast prototyping and quick measurements during development. Rotary Magnetic Holder does not come in the same package as this Click board™, but you can find it in our shop.
The Magneto 14 Click Board™ uses a standard 4-Wire SPI serial interface with a maximum supported clock rate of 25MHz. The PWM absolute output provides a logic signal with a duty cycle proportional to the angle of the magnetic field on the pin PWM of the mikroBUS™ socket. This sensor has two thresholds, MGL and MGH, for low and high magnetic fields. The magnetic field high threshold (MFHT) is indicated over the MGH interrupt pin, together with an additional MGH red LED.
This Click board™ can only be operated with a 3.3V 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.
