OSM-S standard for System on Modules

When it comes to modular embedded solutions, standards are the backbone of any successful development. At bytesatwork, we recognized early on that the demand for standardized yet flexible and forward-compatible modules is continuously growing. In custom projects, we work with a variety of established standards such as SMARC and Qseven. However, for our own product lines, we’ve deliberately focused on the OSM standard – an open, compact, and industry-ready form factor designed specifically for modern embedded needs. In this blog post, we take a closer look at what makes OSM unique, why we’re committed to it at bytesatwork – and what the standard could mean for your next project.

What is OSM?

OSM stands for Open Standard Module – an open, license-free module standard defined by the SGET (Standardization Group for Embedded Technologies). The SGET is an industry consortium that develops specifications for modular embedded systems – including well-known formats like Qseven and SMARC. With OSM, the SGET introduces a standard tailored to compact, solderable modules.

Unlike traditional modules that rely on plug-in connectors, OSM modules are soldered directly to the carrier board . This saves space, increases design robustness, and enables fully automated assembly – a clear advantage for series production.

Why a new standard?

Previous standards have proven their worth in many applications. However, they rely on comparatively large form factors (e.g. 70×70 mm in the case of Qseven) and require dedicated connectors. In modern designs where space, weight, or vibration resistance are key concerns, this can be a drawback.

This is where OSM comes in:

Compact form factor

Four sizes ranging from just 30×15 mm to 45×45 mm

Rugged and vibration-proof

Thanks to the soldered connection, no connector required

High integration density

Up to 662 contacts for modern interfaces like USB 3.0, PCIe, Ethernet, MIPI DSI/CSI, CAN, UART, and more

Pick-and-place compatible

Ideal for automated manufacturing

In short: OSM is made for compact designs with industrial-grade reliability – from IoT sensors to edge computing applications.

Technical Overview

Module Size	Dimensions	Number of Contacts
Size 0	30 × 15 mm	188
Size S	30 × 30 mm	332
Size M	30 × 45 mm	476
Size L	45 × 45 mm	662

OSM at bytesatwork

We’re already leveraging the OSM standard in our product portfolio. This includes our iMX93 OSM-S powered by NXP’s i.MX93 processor – as well as the STM32MP25 OSM-S, built around the latest STM32MP25 dual-core processor from STMicroelectronics. Combined with our DEVKIT , carrier boards, and an open software stack (Yocto Linux, Zephyr RTOS), we offer ready-to-use embedded systems for your projects.

At bytesatwork, we believe: if you’re building embedded systems today, OSM should definitely be on your radar.
