Description
2.8 inch 4 Wire Resistive Touch Panel Screen
Product Description:
The 2.8-inch 4-wire resistive touch panel is a durable and reliable user interface component designed for embedded systems, handheld devices, and display modules.
It detects touch through pressure applied on the top conductive layer, making it ideal for environments where capacitive screens may fail — such as industrial, medical, and outdoor applications.
It can be easily interfaced with most microcontrollers using an ADC (Analog-to-Digital Converter) or a dedicated touch controller IC like the XPT2046, ADS7843, or STMPE610.
Features:
-
4-Wire resistive touch technology (X+, X–, Y+, Y–)
-
Compatible with most microcontrollers and touch controllers
-
High durability for over 1 million touches
-
Works with stylus, gloved, or bare finger input
-
Compact size — ideal for 2.8″ TFT displays
-
Simple analog interface (no special drivers needed)
-
Scratch-resistant surface
