As an operating system, **BlueOS should be run using a card with _at least_ an A1 [Application Performance Class](https://en.wikipedia.org/wiki/SD_card#Performance_ratings)**, to avoid degraded performance and system throttling.

+Critical use-cases are recommended to use A2 cards, and systems intended for onboard recording of one or more video streams should use cards with a suitable [Video Speed Class](https://en.wikipedia.org/wiki/SD_card#Video_speed_class_(V)) rating (and appropriate total capacity) for the expected sustained data rates and file sizes. +{% end %} + Recommended operating system images of the latest stable version can be downloaded here: | Board Hardware | Image File (with Base OS) | Notes |
