DUELink® Smart Electronic Building Blocks

GHI Electronics DUELink is a versatile ecosystem of smart electronic building blocks designed to make physical computing fast and accessible for engineers, makers, and educators. Each module functions as a microcomputer that can run independently or be controlled via simple text commands from host platforms like a PC, Raspberry Pi, Arduino, or micro:bit. Featuring a plug-and-play daisylink architecture, it allows users to chain multiple sensors, actuators, and displays together without soldering, and control them using popular languages including Python, JavaScript, .NET, or drag-and-drop MicroBlocks.

Features and Benefits

• Universal language support: Users can code in preferred language, bridging hardware to Python, JavaScript, .NET C#, or drag-and-drop block coding (MicroBlocks)
• Tethered or standalone operation: Run modules independently using internal DUELink Scripts or tether them directly to a host device such as a PC, Raspberry Pi, or Arduino
• Daisylink architecture: Connect several smart modules in a chain using the proprietary downlink interface without exhausting standard I²C addresses
• Built-in scripting engine: Each module functions as a self-contained mini-computer that can process readable text commands over USB, I²C, or UART
• Zero-install browser development: Begin experimenting in minutes using the online DUELink Console without the need to install complex toolchains, drivers, or IDEs
• Cross-ecosystem integration: Works with non-DUELink modules out of the box, including SparkFun Qwiic, Adafruit STEMMA QT, and Arduino Modulino via I²C JST connectors

Applications

• Engineering: Building rapid prototypes and proof of concepts in minutes versus days at an extremely low cost
• Maker projects: Utilizing a dynamic, plug-and-play system that elevates existing hardware and software knowledge for complex personal builds
• Education: STEM-tailored classroom learning where students can write code and instantly see it come alive, starting from easy block-coding in MicroBlocks to advanced Python projects
