I was really expecting an answer not so great as yours, like "There are the boards ECM-5718, xxx, yyy.", but your answers were much more complete. I really appreciated your message. Again, thank you very much! Best Regards, Rodrigo. P.S: I think a 600 Mhz would suffice for my application because I think this processor can process a 480x240 color image for, basically, threshold processing. Other required processing have few processing power requirements. But for sensor data reading, I would need to have maximum latencies of 20 us. But the data reading processing is very simple and takes much less than 1 us. But anyway, it is not a commercial application. It is just my robot with a sample program for validating the framework developed in my Master thesis. I will not implement it with SBC, but I want to be more specific when arguing that it would be possible to use a SBC and show an example of SBC that could be used. But I really like your message because I may need to develop real applications in future and it is good to see your suggestions. Thank you.
