SigCore UC is a powerful and flexible universal I/O controller built for demanding applications. With hardware designed to accept and generate a broad range of analog and digital signals and fully open-source firmware and software, SigCore UC is equally suited for prototyping, integration, control, automation, education, and experimentation.

SigCore UC eliminates common integration obstacles like signal mismatches, proprietary drivers, and closed ecosystems. It also handles real-world voltages (millivolts to 30 V), logic levels (3–30 V), and industrial standards like 4–20 mA current loops, all with no additional circuitry required. It includes USB and Ethernet interfaces, onboard Modbus TCP server functionality, and developer libraries in both Python and .NET, making it easy to integrate into modern workflows.

Upgrade Your Lab

Whether you’re in a shop or a professional lab environment, SigCore UC lets you take complete control over your workflow. But outside of that, it can be helpful in industrial HVAC or at the heart of QA burn-in racks. Need a sensor gateway or a signal conversion node? It can do that too.

Anywhere you need sophisticated analog or digital signals and require the customizability that only open-source hardware and software can grant, SigCore UC can help you get your work done.

Features & Specifications

• Universal I/O: Accepts a wide range of real-world input/output signals
• Digital inputs: 8 channels, accepts 3–30 V logic (ON at 3V and above)
• Analog inputs: 4 channels, supports millivolts to 30 V and 4–20 mA current loop sensors
• Analog outputs: 4 channels, configurable for 0–5 V, PWM (channels 1 & 2 only), or 4–20 mA current loops
• Relay outputs: 8 isolated SPDT channels, rated 120 V AC at 10 A, with both NO and NC terminals
• Modbus TCP and USB interfaces: Supports real-time control through the bundled software or standard industrial protocols
• Control software: Intuitive Windows application with live signal monitoring, relay toggling, calibration, and configuration
• Embedded PID control: Built-in industrial-grade closed-loop control
• Developer libraries: Fully documented Python and .NET libraries with example code

Open Source

Whether you’re an engineer, researcher, educator, or enthusiast, SigCore UC is designed to empower your creativity, not restrict it. That’s why we’re making it open hardware. We will have a GitHub repo with firmware, software, and hardware files, including the bill of materials, board layouts, and schematics. We hope to have these files posted after the campaign ends.

Developer guides, API documentation, wiring diagrams, and calibration instructions will also be available and maintained in public repositories.
