* If you try to use Fedora on a Raspberry Pi 1, Raspberry Pi Zero, or a Raspberry Pi model A, you will receive the rainbow display. This occurs because your Raspberry Pi is not supported (ARMv6 SoCs architectures are not supported).
=== What desktop environments are supported?
== What desktop environments are supported?
All desktops as shipped in Fedora should work and both 2D and 3D graphics work out of the box.
There is an open source fully accelerated driver for the Video Core IV GPU.
=== Will there be more enhancements to the hardware support?
== Will there be more enhancements to the hardware support?
Yes.
New enhancements will be delivered by the standard Fedora updates mechanism.
New, significant features will be announced by the link:https://fedoramagazine.org/[Fedora Magazine] or the link:http://fedoraplanet.org/[Fedora Planet].
=== What about support for the Raspberry Pi Models A/A+, B/B+ (generation 1), Zero/ZeroW and Compute Module?

NOTE: Fedora DOES support the Compute Module 3 based on the same SoC as the Raspberry Pi 3, but *as the previous generation Compute Modules are based on ARMv6 architecture, they are [#.underline]#not supported#*.
=== What USB devices are supported on the Raspberry Pi?
== What USB devices are supported on the Raspberry Pi?
Most USB-2 compatible devices that are supported in Fedora on other devices.
There are some limitations to the USB bus of the Raspberry Pi hardware as link:https://www.raspberrypi.org/documentation/hardware/raspberrypi/usb/README.md[documented here].

=== Is the onboard Bluetooth supported on the Raspberry Pi 3?
== Is the onboard Bluetooth supported on the Raspberry Pi 3?
Bluetooth works and is stable. The device sometimes has a generic bluetooth address but should work without any configuration.
=== Does sound work?
== Does sound work?
HDMI audio output is included with Fedora, however, the analog port is not yet supported.
Audio output using a USB audio interface should work.
=== Does the add-on camera work?
== Does the add-on camera work?
Not at this time.
There is still ongoing work to support this upstream and to add the appropriated media acceleration support.
=== Does accelerated media decode work?
== Does accelerated media decode work?
No.
The upstream kernel does not support the kernel subsystems required for accelerated media decoding.
=== Does HDMI-CEC work?
== Does HDMI-CEC work?
Yes.
Yes. It's supported using the new upstream CEC support. There's a `/dev/cec0` character device, it can be accessed using any application that supports the IR remote using the `rc-cec` keymap in the `v4l-utils` package, there's also a `cec-ctl` utility for use on the command line.
=== Is the Raspberry Pi Touch Display supported?
== Is the Raspberry Pi Touch Display supported?
Work on the official Raspberry Pi Touch Display is ongoing upstream and initial support is provided in the 4.10 kernel, see: link:https://github.com/anholt/linux/issues/8[GitHub: raspberrypi/linux issues - 7" LCD touchscreen not supported].
Fedora will review any missing pieces for support soon.
The touchscreen driver isn't yet released upstream.
Support for other displays is not currently planned.
=== Is the composite TV out supported?
== Is the composite TV out supported?
The composite TV out is not currently supported in a stable Fedora release but the core support is in the 4.10 kernel.
There is some missing enabling patches which will be added to the Fedora kernel soon.
=== Are the expansion HATs supported?

The first focus HAT to support will be the official Raspberry Pi Sense HAT. This will be documented using the manual process to build and load the overlay to provide access to the onboard devices as a means of demonstrating how this process works for those wishing to use this manual method in the interim. The link to this documentation will be added here once that is complete.
=== The use of config.txt
== The use of config.txt
The `config.txt` is only used for basic configuration at the moment. Because of the use of the opensource vc4 GPU driver, most of the video configuration is done by Linux.
The configuration of HATs using `config.txt` is unsupported but is being actively developed.
=== Are Device Tree Overlays supported?
== Are Device Tree Overlays supported?
There's basic support for overlays in u-boot and the Linux kernel but an overlay manager is not supported upstream.
=== Is GPIO supported?
== Is GPIO supported?
GPIO is supported with the use of libgpiod and associated bindings and utilities.
