Hello,
How can i do to connect 2 mainboard like spider and cerbot.
To have communication between them.
Not Bluetooth or wifi.
Thank you.
Welcome to the forum.
Since you want to connect a Cerbot, I assume it needs to be wireless.
You could have a look here:

Or here is a good starting point for XBee:

The easiest way would be in using the null modem over serial ports.
