Metro Grand Central Max Baud Rate

Hello,
I'm considering using the Metro Grand Central for a project that I am working on, what is the max baud rate of the board? Thanks!

The way I read the datasheet, max baud rate is clock/3, or 40MHz. There might be and additional factor of 2, or maybe 8.
But still “faster than asynchronous comm is ever expected to go. Better pay attention to the physics of your wires.”

Be aware that “Serial” is a direct usb connection to the pc, so it always runs at USB speeds: 6 to 10ish Mbps.
