Highlights
Open Standard Module™ (OSM)
Built on the vendor-independent OSM Size-S specification, designed for future-proof, solderable SoMs. The OSM standard is backed by multiple manufacturers, ensuring scalability, interoperability, and ecosystem longevity.
Ultra-Compact and Solderable
Measuring only 30×30 mm, the OSM iMX91 combines a rugged, connector-less design with optimized machine assembly for reliability and cost efficiency. Its solderable form factor makes it ideal for high-volume production and space-constrained devices without compromising on industrial-grade reliability.
High volume ready
The most affordable Toradex SoM, the OSM iMX91 is designed for applications where volume are critical. It provides a balanced mix of essential interfaces and reliability at an accessible price point.
Optimized for Edge & Industrial IoT
With a lean but well-targeted selection of interfaces, the OSM iMX91 includes only the features that matter most for edge and industrial applications. Its essential connectivity delivers exactly what typical automation, IoT and control systems require. Nothing more, nothing less.
Security Built-In
Featuring Arm® TrustZone® technology, NXP’s EdgeLock® secure enclave, and Secure Boot support, the OSM iMX91 simplifies compliance with modern security standards, including the EU Cyber Resilience Act (CRA).
Power Optimized
Compact and power-efficient, the OSM iMX91 SoM is a perfect fit for IoT gateways, smart sensors, and control units. Its architecture balances performance with low power consumption, enabling always-on devices and battery-powered designs.
Industrial Reliability
The OSM iMX91 SoM is engineered for high reliability in challenging environments and across a wide temperature range, making it ideal for mission-critical applications.
Torizon for Updates, Remote Access and Monitoring
This iMX91 SoM is available with a tightly integrated Torizon Cloud (formerly Torizon Platform) accelerating the development and maintaining your products. Some key features include highly secure and reliable, over the air and offline updates, device monitoring and remote access.
Why Toradex OSM SoMs?
Toradex brings its proven quality, long-term commitment, comprehensive full-stack portfolio and outstanding developer support and documentation to the Open Standard Module™ (OSM) ecosystem. By combining a solderable, ultra-compact form factor with industrial-grade reliability, Toradex OSM SoMs help you simplify production while staying cost-efficient and future-proof.
Torizon
Torizon makes modern, iterative product development easier by seamlessly integrating hardware, an OS, development tools, remote updates, and fleet monitoring. That makes it a scalable solution for devices requiring high reliability and security.
