Overview
The Magneto Click Board™ is an accessory board that comes equipped with a contactless magnetic 360 degree angle position sensor chip termed as AS5048A. The operations of the sensing circuitry of this board are based upon the Hall Effect. Magneto can easily detect the presence of a nearby magnetic field in a 360 degree two-dimensional plane adjacent to the surface of the AS5048A chip.
The angle measurements provided by the Magneto Click Board™ can be precisely down to 0.05' in 14-bit resolution, if an external MCU does the linearization and averaging tasks. The board.
The Magneto Click Board™ carries an AS5048A contactless magnetic angle position sensor. The sensing circuitry relies on the Hall Effect to detect the vector of a nearby magnetic field in a 360º two-dimensional plane parallel to the surface of the chip. AS5048A delivers precise angle measurements down to 0.05º in 14-bit resolution. Its accuracy is not impeded (up to a point) by misalignment, air gap variations, temperature variations, even stray magnetic fields. The PWM outputs the absolute position information. Additionally, the magnet's zero position is programmable (via SPI).
The Magneto Click Board™ communicates with the target MCU through the mikroBUS SPI interface (CS, CLK, MISO, MOSI). Designed to use either a 5V power supply.
IC/Module: AS5048A Rotary Position Sensor
The AS5048A is a 14-bit rotary position sensor/encoder, which measures the absolute position of the magnets rotation angle. In other words, it is a contactless 360
