The Nano Power 2 Click Board™ is a very low power voltage comparator, aimed at portable and battery-powered applications. It allows detecting a difference of two voltage potentials, applied on two input pins. The device can detect differences very precisely, avoiding oscillations that can occur when both input voltages are equal by employing an internal hysteresis.
The Nano Power 2 Click Board™ offers a choice to select one of the input voltages from the internal fixed reference of 1.2V, or by setting both input voltages by the onboard potentiometers.
