Maivin - Modular full-stack AI Vision System
Maivin accelerates AI vision product development from prototype to production while simplifying maintenance and over-the-air updates. Built around a Toradex Verdin Computer on Module, it features an NXP® i.MX 8M Plus Applications Processor, with an integrated Neural Network Processor with 2.3 TOPS. Maivin covers the full-stack, from the camera sensor, enclosure, connectivity, machine learning toolchain, to remote updates and fleet management. Maivin simplifies modern on-device AI at the edge.
Maivin is a close collaboration between Au-Zone, Vision Components and Toradex.
With an optional waterproof enclosure and connectors, Maivin is built for rugged outdoor environments. The dual CAN bus interfaces and a wide input voltage make Maivin ideal for tractor and trailer applications. The optimized NPU enables low-power operation without active cooling over a wide temperature range. A selection of high-quality Sony image sensors with support for HDR help with picture quality in challenging outdoor environments, and an optional cellular modem provides connectivity in the field.
A robust, compact form factor and industrial interfaces like EtherCat, TSN and RS-485 allow you to deploy Maivin in robotics applications. A high-performance Cortex-M7 microcontroller running at 800 MHz makes the system capable of handling even hard real-time computing, while Torizon lets you easily integrate popular robotics frameworks. Built-in support for over-the-air (OTA) updates improves security and streamlines maintenance, and the neural network processor offers high performance without a trade-off in power consumption.
High-performance deep learning inference capabilities provide a modern edge computing solution close to the sensor for the greatest reliability and lowest latency. Maivin’s small size and low cost mean that you can deploy it anywhere on the factory floor. RS-485, an optional second Ethernet port, and support for the EtherCat and Time-Sensitive Networking (TSN) standards all make integration with critical automation equipment fast and easy. Wi-Fi and Bluetooth further expand connectivity to networks and sensors. Built with industrial-grade components, Maivin is designed for 24/7 operation.
Toradex’s proven long-term availability and a well-managed product change process make Maivin an excellent choice for healthcare applications. The hardware and software provide safety and security features, such as ECC memory and frequent cybersecurity updates. Its compact size and flexible camera orientation enable the system to be integrated into small medical and laboratory equipment. Thanks to the modular camera and optics, you can optimize Maivin for your specific application.
A full-stack integrated solution based on production-grade hardware and software components supports rapid prototyping, field testing and validation of your smart vision solution. The modular design makes it simple to customize with alternate image sensor modules, I/O interfaces, enclosures and connectors for different use cases and applications.
Once validated, your design can quickly move to production with available components to avoid costly supply chain delays. Application-level software and core services are then available to support your design in the field with model improvements, remote updates and fleet management.
All major parts of the system are modular. This way, you can optimize the system for your particular use case while taking advantage of a common software and hardware system.
Maivin includes everything from the camera sensor, processing hardware, enclosure, operating systems, deep learning optimization, and development tool, up to fleet management.
Maivin is ready in minutes. The form factor, enclosure and mounting options mean that you’re never tied to your desk: you can easily develop while the system is mounted in the field. Torizon and eIQ DeepView support you by accelerating development progress.
The core components are ready for volume production — just choose the optimum System on Module, camera sensor, enclosure and back connectors for your use case. Need more customization? Get in touch and we’ll be happy to help.
Maivin is supported by the Torizon platform, providing a modern embedded Linux operating system with frequent updates, as well as seamless integrated remote updating and fleet management options. The system is optimized for a modern development workflow and simplified maintenance.

Torizon OS (formerly TorizonCore) is an easy-to-use, industrial-grade embedded Linux system. Torizon is ready to use right out of the box and maintained by Toradex with frequent updates. Torizon integrates with a wide range of development tools and frameworks, even beyond pure deep learning. Do you need a UI, soft PLC, motor control or web interface? The Torizon ecosystem has you covered. Torizon also includes required drivers for the best performance and a fast time to market.
Camera and ISP support
In collaboration with Vision Components, Torizon includes support for the camera and image signal processor (ISP) on the i.MX 8M Plus, allowing for advanced image preprocessing, such as color conversion, geometry corrections, HDR, gamma correction and much more.
The Torizon Cloud (formerly Torizon Platform) includes a robust, automotive-grade, secure remote update system that’s fully integrated and simple to use. The system is designed to be safe even in the event that a device loses power in the worst possible way. It allows you to update not only your neural network, but also your application and the operating system itself.
Torizon includes a fleet management system, so you’ll always know the status of your system in the field. An intuitive web interface allows you to get a system overview, mange devices, trigger updates and get inputs to continuously improve your product.
eIQ Portal™ is a free, GUI-based development tool for training, validating and optimizing machine learning models for the i.MX 8M Plus neural processing unit (NPU). Design workflows support importing an already trained model or importing data to train a new model for deployment.
DeepView supports extensions to the eIQ workflow which are optimized for the DeepViewRT runtime inference engine. Integrated solutions are optimized to leverage the hardware acceleration cores in the i.MX 8M Plus for maximum performance and extended functionality. This includes a vision processing pipeline, custom models and application-level solutions. You can also choose to have standard modules augmented with Au-Zone engineering services for custom software or hardware development.
Maivin is available now as sample directly from Au-Zone.
One of the main differences to the final version is that the sample uses a OnSemi AR0521 5MP rolling shutter color camera sensor instead of the Sony sensor. The reason is that we are working on a new ISP driver which can be mainlined - however this driver is not ready. AR0521 comes with integrated ISP and does not require this driver
