I have been looking at this board from a company called Next Thing. Note that their website does NOT end with
.com,
it ends with
.co
They have a Kickstarter campaign for a $9 board that will have an ARM processor, WiFi, Bluetooth, and composite out. Then more expensive boards have VGA or HDMI out, which, if its embedded, has no need. I do not understand (yet) what they are proposing for audio.
Biggest issue is, not due until May 2016, which will probably mean November, 2016.
