Boardoza SM351LT Hall-Effect Sensor Breakout Board

The Boardoza SM351LT is a high-sensitivity hall-effect sensor module designed for lid, door, and drawer position detection. It features omnipolar sensing, activating with either pole of a magnet. With a push-pull output, the module eliminates the need for an external pull-up resistor, simplifying integration into various applications.
