Frequently Asked Questions
The OSM iMX91 is a Toradex System on Module engineered for high‑volume industrial and IoT applications, including IoT gateways, smart sensors, PLCs, industrial controllers, handheld devices, and edge computing devices. It is purpose‑built for headless Linux systems where compute efficiency, ruggedness, and long‑term availability matter more than rich multimedia.
This module integrates CPU, memory, storage, connectivity, and security into a ready‑to‑use 30 × 30 mm solderable module that simplifies hardware design and accelerates product development.
This module integrates CPU, memory, storage, connectivity, and security into a ready‑to‑use 30 × 30 mm solderable module that simplifies hardware design and accelerates product development.
OSM (Open Standard Module) is an SGET‑maintained open specification for solderable, LGA‑style System on Modules. The OSM iMX91 follows the Size‑S variant with a 332‑contact grid in a 30 × 30 mm footprint.
Because OSM is vendor‑neutral and royalty‑free, you can design your carrier board once and swap between compatible modules from different vendors or processor families — protecting your hardware investment over long product life cycles, while gaining the reliability and cost advantages of a soldered footprint.
