Aideepen | Single Channel Digital Potentiometer Module - 5K/10K/20K Adjustable Resistor with 3-Digit LED Display for Precision Control

Features:1. Integrated LED display shows resistance values in real time, providing intuitive and clear adjustment without external measurement tools.2. Supports multiple resistance values (5K/10K/20K) to accommodate diverse circuit application needs.3. Knob operation balances adjustment efficiency with precise parameter readability.4. Industrial-grade design with high-temperature resistance and anti-interference capabilities ensures stable, reliable operation in complex environments.5. Standard interface design enables easy installation and plug-and-play functionality, ideal for laboratory and development settings.Product Description:This integrated electronic adjustment device combines an adjustable potentiometer with a digital display. The mechanical knob adjusts the potentiometer resistance, while the digital display shows the current resistance value in real time. Equipped with a three-digit display, it simultaneously shows the current resistance on the numeric display when rotating the potentiometer, eliminating the need for external meters and simplifying monitoring procedures. Centered on the “adjust-display-expand” core concept, it streamlines resistance adjustment and simplifies monitoring workflows.The display format is a three-digit LED.

Due to inherent characteristics and manufacturing tolerances, potentiometer resistance values (measured between fixed terminals A->B) typically exhibit an error range of ±20%. This tolerance is generally considered acceptable within the electronics industry. Most manufacturers, including ours, produce potentiometers with resistance tolerances between ±5% and ±10%. This margin of error has minimal impact on most applications.Potentiometer Definition:A variable resistor that adjusts resistance, typically featuring three terminals: two fixed points (A, B) and a sliding output point (W). During adjustment, the resistance between A->W is inversely proportional to that between B->W. When A->W resistance increases, B->W resistance decreases. This module displays the resistance between B->W.Product Listing:1X ModuleApplication Scenarios:1. Electronic Experiment Learning: In circuit fundamentals education, it visually demonstrates the relationship between potentiometer resistance changes and circuit parameters (e.g., current, voltage), aiding understanding of variable resistor principles and enhancing experimental interactivity.2. Circuit Debugging & Calibration: During electronic device R&D debugging, adjust potentiometer resistance while monitoring real-time parameters displayed on the LED display to calibrate circuit metrics like bias voltage, amplification factor, and filter thresholds. Reduces reliance on external multimeters and streamlines workflow.3. DIY Electronics Project Development: Compatible with maker projects like volume control modules, brightness controllers, and motor speed circuits. Connects to development boards (e.g., STM32) via header pins for manual resistance adjustment and data acquisition, streamlining project setup.4. Device Parameter Configuration: Serves as a parameter adjustment component in small instruments and sensor calibration equipment. By rotating the potentiometer to set values (e.g., temperature alarm thresholds, pressure trigger points), the LED display provides real-time feedback of the set values, enhancing operational convenience.
