Voltmeter Click Board
The Voltmeter Click Board™ is a MikroBUS add-on board for measuring voltage in an external electric circuit. The board is designed to measure Direct Current only, and has a measurement range from 0 to 24V (it's possible to measure both positive and negative polarity).
The design of the board is based on an OpAmp set up as a differential amplifier with a buffered input. Two on-board screw terminals (probe+ and probe-) are bringing in the current, which then flows through a row of four resistors. A voltage ,.
