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 is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- FPC
- FPC stands for flexible printed circuit, a flat flexible cable or connector style often used where space is tight. It matters because this breakout needs the correct pin count and pitch FPC cable to connect reliably to the display or high-speed interface.
- 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 chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
