I did not know that, OK. So the board markings are wrong, I tried to read the manuals and find help through it but it is not written there. I plan to flash the 310p, I take it that it is the best proven and safest so far? I just want to take my step one a time to fully understand and get the full potential of this board and just want to be cautious. And thanks for a great thread, I now have a much better understanding of this board since building it three days ago.
