UNI HALL click is a simple solution for adding an unipolar Hall switch to your design. It carries the Melexis US5881 unipolar Hall-effect switch and a 74LVC1T45 single bit, dual supply translating transceiver. The unipolar Hall effect sensor on UNI HALL click is sensitive to north pole magnetic fields—when exposed to such a field, it outputs a LOW logic level. Otherwise the output is a HIGH logic level. It can be employed in a wide variety of scenarios—anywhere where a magnet can be used to infer speed, position, or other properties of the target object. UNI HALL click communicates with the target board through the mikroBUS INT line. It's designed to use either a 3.3V or a 5V power supply.
