I need a small Linux SBC that has at least 4 serial ports (easy expandability to more is a big plus), and one ethernet port. I need it to have 32 MB of RAM and 4 MB of flash disk. I plan to use it as a serial device server accessible via ethernet.
It needs to be as small and low-power as possible, since it will be deployed in remote solar-powered surface buoys and underwater containments.
I am currently researching this, and if anyone can give me a pointer in the right direction, I would be grateful!
Thanks.
