Thanks for your help. I ordered * Libre Tea Computer Card * Micro Desktop Housing for Computer Card
I’ve never even seen this board, so why did I order? I’ve already got a few SBCs here that aren’t quite right. This new computer card is a compact board, with a great specification at a reasonable price. And I’m looking forward to feeling the benefit of these improvements over other SBCs. * FSF certification. That means a lot of people a lot smarter than me have checked the system. I can expect it to just work. * the card housing. I can put this in my pocket, without ripping bits off the motherboard. * That PCMCIA socket. That’s so easy to use - all you got to do is push it in and pull it out. And of course, it can run my favorite Linux distros. Thanks for putting together such a great product. > On 17 Jul 2016, at 15:25, Luke Kenneth Casson Leighton <[email protected]> wrote: > > --- > crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68 > > > On Sun, Jul 17, 2016 at 12:30 PM, Nick Hardiman > <[email protected]> wrote: > > >> So if I got this right, I can set up a card with network access in three >> ways - a minimal standalone setup, a full desktop setup, or a PCB for many >> cards.
