As more and more people start to develop software in Haskell for single
board computers, I created the HaskellWiki pages Arduino, ARM,
Raspberry Pi, BeagleBoard and PandaBoard.
I hope experts on the matter will give these pages more body (for example,
describe what is necessary to get Haskell programs running on these
platforms) and add links to relevant web pages. The PandaBoard page needs
an image, I couldn't find one with public domain license. If you don't
know how to edit HaskellWiki pages, read the contribute page first.
To get your appetite wet, if you are not involved in this yet, take a look
at the Arduino Weather Clock; this is really a fun project.
