The DIGI POT 4 Click Board™ is a digitally controlled dual potentiometer with a resistance of 10Kohm. It has a 10-bit resolution, allowing for a very smooth linear wiper positioning through 1024 steps. The digital wiper position can be controlled via the SPI interface. The DIGI POT 4 Click Board™ 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 is on - just like its mechanical counterpart.
