X9C103S Digital Potentiometer Module

The X9C103S Digital Potentiometer Module is a programmable 10KΩ digital resistor module with 100 adjustment steps. It allows electronic resistance control using digital signals instead of manual rotation. The module features non-volatile memory to retain settings after power loss and is compatible with Arduino, ESP32, ESP8266, STM32, and other microcontrollers for signal adjustment, calibration, and automation applications.
