I'm looking for a Linux capable Single Board Computer, which I can use for Machine to Machine communications.
It needs to be small/low-power (SKY and Pico-ITX form factors are fine), but the crucial bit is cellular/LTE connectivity, USB host, and Serial/UART (a few GPIO's would be nice too).
I know the BBB has an M2M cape, and that's one good option, but the BBB is so hard to come by these days.
I'm open to suggestions of off the shelf solutions, and also something that could take an LGA, mPCIe, or M.2 module.
looks good (and cheap!), but it seems to be unsupported, and nearing end-of-life.
is interesting too.
