Hårdvaruversion

Hårdvaruversion, or hardware version, is a designation used to distinguish different physical revisions of a product’s design over its life cycle. It typically refers to changes in a device’s printed circuit board (PCB), components, connectors, enclosures, or mechanical assemblies that affect function, performance, reliability, or manufacturability. These revisions are tracked separately from software or firmware versions and may be used in conjunction with them.

Labeling and numbering conventions vary. Versions are usually indicated by a revision number or letter (for example 1.0, 1.1, 2.0 or A, B, C). Some products apply separate major and minor revisions, while others append suffixes to the model number. Documentation often includes a revision history or change notice, and the bill of materials (BOM) is updated accordingly. Markings on the device, packaging, or accompanying manuals may reveal the exact hardware version.

Impact and usage are practical considerations. Hardware versions affect compatibility with peripherals, spare parts, and firmware; certain accessories or features may only function with newer revisions. When repairing, sourcing parts, or applying updates, identifying the exact hardware version is essential to ensure correct parts and documentation. Different revisions can also reflect improvements in manufacturability or reliability and may accompany changes in testing and certification.

Lifecycle management of hardware versions helps manufacturers, distributors, and users track changes, manage compatibility, and plan support. In practice, it is a key element for engineering, procurement, and service processes.
