ALLNET ALL-D-39 Touch Screen Kit

The ALLNET ALL-D-39 touch screen kit is a compact 2.4" diagonal display module designed for use with Arduino platforms. Weighing approximately 110 g, the kit provides a capacitive touch interface and a screen size suited to small embedded projects, control panels, and portable prototypes. The module connects to standard Arduino-compatible boards and offers a responsive touch surface to simplify user interaction in applications where space is limited.

Advantages

The touch screen kit combines a small footprint with a responsive touch interface, enabling intuitive control in compact systems. Its 2.4" diagonal display balances readability and space efficiency, while the lightweight construction supports portable and battery-powered designs. Compatibility with Arduino ecosystems allows straightforward integration into existing projects and rapid prototyping.

Suitable for (tasks / use cases)

• Embedded control panels for home automation or appliances
• Portable prototypes and handheld devices
• User interfaces for Arduino-based sensors and actuators
• Educational projects and interactive demonstrations
• Compact monitoring displays for status information

Key specifications

• Display diagonal: 2.4 inches
• Form factor: compact, lightweight module (~110 g)
• Interface: Arduino-compatible connection and control
• Input type: touch-sensitive display (capacitive or resistive depending on model implementation)
• Typical use: low-power embedded applications and prototypes

How to use

Mount the touch screen kit to a compatible Arduino board following the module's pinout and wiring instructions. Install any required libraries and touchscreen drivers in the Arduino IDE, then upload example sketches to verify display output and touch input. Design the user interface within the available resolution and ensure touch coordinates are calibrated if the library provides a calibration routine. Place the module in an enclosure or mounting panel to secure it for permanent installations.

Recommendations

Use stable power supply lines and proper wiring to avoid noise affecting touch responsiveness. Test touch calibration during development and protect the display surface from scratches or liquids when used in portable or industrial environments.
