Bi Hall Click Board™

The Bi Hall Click Board™ is a simple solution for adding a bipolar Hall switch to your design. It carries the Melexis US2882 bipolar Hall-effect switch and a 74LVC1T45 single bit, dual supply transceiver. A bipolar Hall effect sensor is sensitive to both north and south pole magnetic fields.

The Bi Hall Click Board™ outputs a HIGH logic level when exposed to a south pole magnetic field, and a LOW logic level when exposed to a north pole magnetic field. When removed from a magnetic field, the logic level stays in its previous state. The US2882 IC integrates a Schmitt trigger with hysteresis, thus preventing output oscillation near the switching point between alternating magnetic poles.

The Bi Hall Click Board™ communicates with the target board through the mikroBUS INT line. It's designed to use either a 3.3V or a 5V power supply.
