What is a Qseven Module?
Qseven is a standardized, compact computer-on-module (COM) form factor designed for embedded and industrial applications. It is not a complete computer system but a core processing module that provides the CPU, memory, storage controllers, and essential I/O on a small, unified board. This module is then plugged into a custom-designed carrier board that provides the specific connectors and expansion required for the final application. The standard defines a 70mm x 70mm size and a high-density MXM 3.0 connector for reliable, high-speed interfacing.
Key Specifications and Technical Details
The Qseven specification is defined by the Standardization Group for Embedded Technologies (SGET). Its primary technical characteristics include:
-
Form Factor: 70mm x 70mm (2.76" x 2.76").
-
Connector: A single 230-pin MXM 3.0 connector, ensuring a robust and vibration-resistant connection to the carrier board.
-
Power: Typically operates on a single +5V or +12V power supply, supporting low-power processors ideal for fanless designs.
-
Standardized Interfaces: The module provides standard signals for display outputs (LVDS, HDMI, DisplayPort), storage (SATA), networking (Gigabit Ethernet), USB, audio, and PCI Express lanes. This allows system designers to create custom carrier boards without designing complex CPU circuitry.
-
Thermal Management: Designed for passive cooling, enabling completely silent and reliable operation in harsh environments.
Use Cases and Applications
Qseven modules are engineered for longevity, stability, and deployment in demanding conditions. Their primary applications include:
-
Industrial Automation: As the brains of PLCs, HMIs, machine vision systems, and robotic controllers.
-
Digital Signage & Kiosks: Powering interactive displays, information terminals, and point-of-sale systems where space is limited.
-
Medical Devices: Used in diagnostic equipment, patient monitors, and imaging systems requiring reliable, long-term component availability.
-
Transportation & In-Vehicle Computing: For fleet management, infotainment, and telematics systems that must withstand vibration and temperature extremes.
-
IoT Gateways: Aggregating and processing data from edge sensors in smart city, agricultural, and manufacturing settings.
