Hi, i am looking for a big embedded board shop online, do you know one ?
Is it unclear what you are looking for. If you tell us more specifically about what you are trying to find and the problem you are trying to solve, we might be able to offer a helpful suggestion.
I am making a robot and need a embedded board like 1ghz CPU and 1go RAM minimum with 2 USB port 2.0 or 3.0. I need this one is a free hardware because i want to write from scratch its OS, so i need its datasheet.
I am not sure exactly what you are looking for, but we do not carry any open-source boards like that. You might find something with a Google search for "open-source Linux board".
