## Pixhawk Standard
|

|

A Pixhawk board is one that conforms to the Pixhawk standards. These standards are laid out on [http://pixhawk.org](http://pixhawk.org/), but at high-level require that the board passes electrical tests mandated by the standard and the manufacturer has signed the Pixhawk adopter and trademark agreement.

|

PX4 generally only supports boards that are commercially available, which typically means that board standards released within the last five years are supported.

FMUv5 and onwards have an electrical sensing mechanism.
|
||||
This sensing coupled with optional configuration data will be used to define hardware’s configuration with respect to a mandatory device and power supply configuration. Manufacturers must obtain the VER and REV ID from PX4 board maintainers by issuing a PR to ammend the [DS-018 Pixhawk standard](https://github.com/pixhawk/Pixhawk-Standards) for board versions and revisions.
