A 4-wire resistive touch screen digitiser (originally designed for the Nintendo DS Lite) that works with a stylus or fingertip. It can be used with any microcontroller that has 2 digital pins and 2 analogue input pins, making it easy to add touch input to your projects — either as a standalone touch panel over a paper overlay, or attached to an LCD for a DIY touch display.
Key Features
- 4-Wire Resistive Touch – Works with stylus or finger input
- 3.7" (95 mm) Diagonal Active Area – Compact touch surface
- Simple Interface – Requires only 2 digital and 2 analogue pins
- 1.0 mm Pitch FPC Connector – Breakout board recommended for breadboard use
- Pressure Detection – Can detect touch presence and pressure level
Specifications
- Overall Dimensions – 62 × 76 mm (2.45" × 3"), 1.2 mm thick
- Active Diagonal – 95 mm (3.7")
- Resistance – 600 Ω across X pins, 300 Ω across Y pins
- Connector – 1.0 mm pitch FPC
Ideal For
- DIY touch-activated displays
- Touch control panels with paper overlays
- Arduino and microcontroller projects
Package Contents
- 1× Resistive touch screen (Nintendo DSL digitiser)

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- FPC
- FPC stands for flexible printed circuit, a thin flat flexible cable or connector style often used where space is tight or some movement is needed, commonly for displays, cameras and other high-density connections. Connecting to an FPC connector generally needs a matching cable with the correct pin count, pitch and contact orientation.
- LCD
- LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
