Description:

Handheld devices from OneNetbook, AOKZOE, AYANEO, And OrangePi provide fan readings and fan control through their embedded controllers.

Currently supports OneXPlayer devices, AOKZOE, AYANEO, and OrangePi handheld devices. AYANEO devices preceding the AIR and OneXPlayer devices preceding the Mini A07 are not supportable as the EC model is different and do not have manual control capabilities.

Some OneXPlayer and AOKZOE models have a toggle for changing the behaviour of the “Turbo/Silent” button of the device. It will change the key event that it triggers with a flip of the tt_toggle attribute. See below for boards that support this function.
