MIKROE-1886 Magneto Click Board™

MikroElektronika presents a contactless magnetic position sensor board featuring the ams AS5048A

Image of Mikroelektronika MIKROE-1987 3D Hall Click™ BoardThe MikroElektronika MIKROE-1886 Magneto click boards feature the AS5048A contactless magnetic angle position sensor from ams. 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. The AS5048A magnet’s zero position is programmable via serial peripheral interface (SPI). This click board provides 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. Magneto click communicates with the target MCU through the mikroBUS™ SPI (CS, CLK, MISO, MOSI). It is designed to use a 5 V power supply.

The ams AS5048 is a 14-bit, high resolution, 360° angle position sensor. The sensor measures the absolute position of the magnet’s rotation angle and consists of analog digital converter, digital signal processing, and Hall sensors. The zero position can be programmed via SPI or I²C command; a programmer is no longer needed. This simplifies the assembly of the complete system because the zero position of the magnet does not need to be mechanically aligned. The AS5048 comes in a temperature range of -40°C to +150°C which makes it ideal for industrial applications.
