X9C103S Digital Potentiometer Module – DC 3–5V 10K Adjustable for Arduino

The X9C103S Digital Potentiometer Module – DC 3–5V 10K Adjustable for Arduino Projects is a digitally controlled potentiometer that enables fine-grained analog control in microcontroller applications. With a resistance range of 10K ohms, this module is ideal for adjusting signal levels, modifying reference voltages, and tuning audio or sensor circuits in real time without mechanical wear and tear.

At the heart of this module is the X9C103S chip, featuring 99 discrete resistive elements controlled via a three-wire digital interface (CS, INC, and U/D). The module also integrates non-volatile memory, allowing it to remember the last set wiper position even after power loss. Compact and efficient, it fits perfectly into projects with limited space and works seamlessly with Arduino, ESP32, Raspberry Pi, and other platforms.
