The X9C103S Digital Potentiometer Board Module is an electronically controlled variable resistor that allows resistance adjustment through digital signals instead of a mechanical knob. Based on the X9C103S digital potentiometer IC, the module provides a total resistance of 10kΩ with 100 programmable wiper positions, enabling precise and repeatable resistance control.

The module features non-volatile memory, which stores the last wiper position even after power is removed, making it ideal for applications requiring retained settings. It can be controlled by microcontrollers such as Arduino, ESP32, STM32, and Raspberry Pi Pico using a simple control interface.

This digital potentiometer is widely used in audio control, programmable power supplies, sensor calibration, LCD contrast adjustment, and automated electronic systems where manual potentiometers need to be replaced with software-controlled resistance adjustment.
