LIN HALL Click carries an MLX90242 linear Hall sensor IC (with built-in active error correction circuitry) and an MCP3201 12-bit ADC. It outputs a signal that is proportional to the flux density of a magnetic field—a north magnetic field will increase the output value while a south magnetic field will cause it to decrease. The ratiometric output allows you to infer the linear or rotary position of a target object by placing magnets on it. LIN HALL Click communicates with the target board through the mikroBUS™ SPI lines (CS, CSK, MISO). The board is designed to use either a 3.3V or a 5V power supply.
