The complete DUELink ecosystem is available to order immediately through our official launch partner, DigiKey. Browse the full module lineup and place your order at digikey.com.

DUELink smart modules speak plain text — add sensors, displays, motors, and communications to any board you already have, in any language, without soldering or writing drivers.

Full specifications, documentation, and project tutorials are available at duelink.com.

GHI Electronics has released a VS Code extension for TinyCLR OS, bringing IntelliSense, deploy, and step-through debug to every SITCore board — from the compact FEZ Stamp to full System on Modules.

The extension works the same way developers expect from the Visual Studio counterpart: write C#, hit deploy, set breakpoints, and inspect variables on real hardware. The extension currently runs on Windows.

Community spotlight: Tiny MQTT Broker​

Developer Skeller used the release as an opportunity to port the Eclipse Paho M2Mqtt broker library to TinyCLR OS, making a fully managed MQTT broker available for SITCore devices. The project is open source and available on GitHub.

Download the VS Code extension and get started at docs.ghielectronics.com.

TinyCLR OS has been running .NET on thousands of products in industries around the world. With a clean year since the previous release and minimal issues filed, we are publishing a commercially-stable refresh — version 2.4.0.1000.

What's new in 2.4.0.1000​

HDMI at higher resolution — A 120 MHz SDRAM overclock option is now available, enabling 1280×800 output for customers who need it.

WPA/WPA2 on both AP and Client — Wi-Fi mode now supports WPA/WPA2 security in both access-point and client configurations.

TLS and HttpListener fixes — Secure network connection improvements address a connection issue with HttpListener.

Visual Studio 2026 is fully supported.

DUELink is ready for your innovations. One year after the original teaser, GHI Electronics is announcing the full launch of the DUELink platform — smart modules that work with every popular hardware system and every popular coding language.

DUELink is compatible with Raspberry Pi, Arduino, ESP32, micro:bit, and any other board you already have. It supports Python, JavaScript, .NET, MicroPython, and more. The key idea is simple: DUELink is not designed to replace what you have — it is designed to work with what you already use today.

Every module speaks the same plain-text protocol over USB, SPI, I2C, or UART. Code written for one module works the same on the next. The catalog covers sensors, displays, motors, storage, communications, and education kits — and it keeps growing.

Full details, documentation, and examples at duelink.com.

We discontinued the all-beloved Gadgeteer modules years ago, but something new is in the works — and it goes much further than Gadgeteer ever did.

Meet DUELink — Dynamic Universal Expandable Link. Where Gadgeteer required a specific mainboard and a specific host language, DUELink works with anything: Arduino, Raspberry Pi, PC, phone, ESP32, micro:bit. It speaks over USB, SPI, I2C, and UART, and it supports Python, C#, JavaScript, and more.

The software infrastructure is in place — internal scripting engine and host libraries for Python, JavaScript, and .NET are ready. The BigBang module is the foundation: a versatile board that serves as the blueprint for the entire catalog.

DUELink is also compatible with the Adafruit STEMMA and SparkFun Qwiic ecosystems, and uses 5mm-pitch mounting holes — familiar territory for anyone who built with Gadgeteer.

A full launch announcement is coming. In the meantime, more details at duelink.com.

Industrial control is evolving rapidly. While Modbus remains a staple, the shift to EtherNet/IP is gaining momentum — and TinyCLR OS now supports it.

A note on the name: in industrial contexts, IP stands for Industrial Protocol, not Internet Protocol. The protocol creators knew exactly what they were doing.

TinyCLR OS now includes EtherNet/IP support in both Adapter and Scanner modes. The feature is currently experimental — GHI Electronics is actively collecting feedback on commercial applications to shape the next iteration.

Due to resource requirements, EtherNet/IP is available on SITCore SC20 devices only and is not supported on SC13.

Endpoint v0.1.8 extends the platform beyond the Endpoint Domino board to other Linux-based hardware. The release has been tested on BeagleBone Black and Raspberry Pi 4.

Use Endpoint Config to automatically install .NET on a compatible board, then deploy and debug .NET applications using the Endpoint extension in Visual Studio or VS Code — the same workflow as the Endpoint Domino.

For production use, the official Endpoint Domino board offers broader peripheral support — CAN, ADC, digital signal, RTC, USB, SD, display, IFU, watchdog, and camera — and boots in under 5 seconds.

4iPlatform builds industrial IoT and automation solutions on GHI Electronics hardware. Their systems collect production data directly from machinery on the plant floor, turning raw machine data into reliable operational information.

4iDASH gathers real-time data from production lines, enabling managers to make decisions based on actual output rather than estimates.

Their PLT (Position Tracking System) continuously tracks the position and status of ladles and heavy equipment in metals manufacturing. The WMS (Warehouse Management System) enables real-time inventory management and asset tracking from the plant floor. An RFID Reader ties into both PLT and WMS workflows.

Endpoint v0.1.3 adds Python support — not MicroPython, but the full CPython 3.10 implementation. Every standard library, every package from PyPI, running directly on Endpoint hardware.

The Endpoint platform already supports full .NET 8. Python 3.10 extends that reach to the large community of developers who work in Python, giving both ecosystems access to the same hardware, the same peripherals, and the same remote deploy and debug workflow from VS Code.

Endpoint v0.1.2 ships four new capabilities: OpenCV support, custom boot screen, faster deployment, and Avalonia UI support.

OpenCV integration is experimental in this release — GHI Electronics is actively collecting use case feedback for AI on a .NET-focused device. If you have an application in mind, share it on the forum thread.

Avalonia UI brings a cross-platform .NET UI framework to Endpoint, enabling rich graphical applications on the device display.

Custom boot screen and deployment speed improvements round out the release.

Endpoint Domino is now available, bringing the full .NET 8 framework to embedded hardware. CAN, analog, NeoPixel, and signal processing libraries extend what's already in the .NET ecosystem — deploy and debug remotely from Visual Studio or VS Code over USB.

SITCore and Endpoint are complementary platforms in the .NET C# space. Endpoint runs a full Linux-based multi-process architecture with the complete .NET 8 runtime — ideal for applications that need the breadth of the .NET ecosystem. SITCore runs TinyCLR OS, a tightly controlled, commercially-proven system optimized for security, stability, and long product lifecycles.
