µQseven System-on-Module. 1.2 GHz Quad-core ARM Cortex-A7 featuring the Allwinner A31 application processor


The A31-µQ7 is the first system-on-module for demanding industrial applications that brings the performance of today’s tablet-processors to the industrial embedded applications: based on the well-known Allwinner A31 application processor, featuring 4 ARM



Standard pin-out and small form-factor

Measuring a space-saving 40mm x 70mm and adhering to the industry-standard Qseven pin-out, the A31-µQ7 is a low-risk choice for developing future-proof devices. It features embedded peripherals, advanced hardware-security and fast processing to create connected industrial devices with rich user interfaces.


Designed and supported in Vienna, Austria

Every module we design, is backed by our expertise in system-level design, embedded software engineering and performance engineering. Our engineers support industrial end-users and maintain development tools for semiconductor vendors. Our experienced teams can augment your in-house design resources to bring your design to market faster.


Linux 4.x and Debian 8 supported

Working with our modules, you will appreciate the feature-packed and up-to-date Linux support out of the box. As we build our board-support from scratch, we are independent from semiconductor vendor release cycles to provide up-to-date Linux versions.


State-of-the-art security for your assets.

The A31 µQ7 is the first system-on-module designed to specifically address security and asset protection using an EAL4+ certified security module. A GlobalPlatform 2.2.1 compliant JavaCard environment provides a trusted foundation for security applications including digital asset protection, secure key-storage and remote device authentication.


Android supported

Based on first-hand experience with using Android in challenging industrial applications, we can offer support for Android on request and provide a customized board-support packages. We understand your requirements, whether you need a kiosk application or a secure container for untrusted code.


Accelerate your application development with the A31-µQ7 development kit.

Whether you have designed with the Qseven form-factor before or are new to developing with a system-on-module, the A31 µQ7 development kit includes everything to get you started quickly. Building on the Mini-ITX base-board, you can start prototyping your application immediately.

Connect a monitor via HDMI, attach a LCD panel via LVDS, interface with USB peripherals or plug in a hard-disk… our reference design has you covered, so you can focus on your application development. We’ve made sure to include everything in the box that you may need to start, so you won’t even have to search for a compatible power-supply or a serial cable.
