An Kit for developing RoarAudio based hardware should be created (meta ticket)

[ph3-der-loewe]

There should be a kit for developers to help them develop RoarAudio based hardware.
The following stuff should be possible with the board:

• Use it as network based sound/MIDI/DMX controler.
• Run standard RoarAudio software like libroar and roard.
• Run specific RoarAudio software for the kit.
• Run own software.
• Compile on the kit so no cross compiler is needed.

The following interfaces are needed:

• Power (best: 9V..15V DC with internal regulators, optionally powering via USB)
• Status LED(s) (Power,...)
• Ethernet
• At least one stereo in and out.
• USB (host controller)
• Standard buses (I²C, SPI, A²C, ...; exact list to be defined later)
• GPIO (number to be defined later)
• Maybe some used defined LEDs and switches.

The board needs to come with a secure case and high voltage parts must not be included.

The following protocols need to be supported:

• DHCP (client)
• DNS (client)
• HTTP (client)
• FTP (client)
• SSH (server + client, scp, sftp)
• NTP (client)
• RoarAudio (depending on running software)
• RPLD (depending on running software)
