DGT Board

Hello everyone
I was going to buy a DGT chessboard.
I have seen that there are two types: USB and Bluetooth.
What I'm interested in doing is a few games against some engines and some online games.
I would also like to avoid turning on the pc or
when turned on, do not look at the monitor.
Apparently, buying a DGT 3000 watch should show the engine moves without looking at the monitor. Or you could even avoid turning on the pc with a Rasbarry.
Now that I understand some things you can only do it with the Bluetooth keyboard.
With the USB keyboard what can you do about everything I said?

The DGT needs a computer to make moves... its not a smart board.

You can have the computer talk and speak the moves so you do not have to look at the computer.

Or, you can purchase the DGT Pi chess clock, this clock has a built in computer.

Hope this answer the questions you have.  You might consider contacting DGT as well.
