[Trisquel-users] any FOSS alternatives to raspberry pi?

[sora]

I am currently using a raspberry pi but it is non-free hardware and  
firmware(bootcode) the software has binary blobs and the RPI foundation seems  
to include licensed wolfram and java as default installed. Although there are  
projects on reverse engineering bootcode to make it FLOSS but it appears to  
take looooonng. I bought it since it is the only thing available that can be  
easily bought at a low price ($48). I am looking for alternatives that is  
free open source software and hardware that is low cost too.
