Force Click Board

The Force Click Board™ is a mikroBUS add-on board with circuitry for implementing Interlink Electronics Force Sensing Resistors into your projects (with a single zone force sensing resistor included with the Click Board™). The Force Sensing Resistor is a thin sensor made of two membranes that are separated by a spacer around the edges. When pressed, the gap between two membranes gets closed. This shorts the two membranes together, with a resistance that is proportional to applied force. The outputted analog voltage is thus a measure of force applied. The force sensitivity range is from about 0.2N to 20N (although it depends on the implementation). The Force Click Board™ communicates with the target MCU through the mikroBUS AN pin. It is designed to use either a 3.3V or 5V power supply.
