SunRobotics X9C103S DC 3-5V Digital Potentiometer Board Module for Arduino Electronic Components Electronic Hobby Kit

This is DC 3-5V X9C103S Digital Potentiometer Board Module for Arduino. The X9C103 are digitally controlled (XDCP) potentiometers. It consists of a resistor array, wiper switches, a control section, and non-volatile memory. The wiper position is controlled by a three-wire interface. The potentiometer is implemented by a resistor array composed of 99 resistive elements and a wiper switching network. Between each element and at either end are tap points accessible to the wiper terminal.
