DIGI POT 4 click is a digitally controlled dual potentiometer, with the resistance of 10KΩ. It has a 10bit resolution which allows for a very smooth linear wiper positioning through 1024 steps. Digital wiper position can be controlled via SPI interface. DIGI POT 4 click also features a non-volatile durable EEPROM memory for storing the wiper position, which means that the device can restore its last position after the power on - just like its mechanical counterpart. The main advantage of the digital potentiometers over the mechanical ones is that they can never wear out.
