I am using the hardware, but not the IDE for this little project. I would like to use the USB interface on the M2560 to talk to the PC terminal program, but I am not sure what speed the thing talks at natively. I know that you can set up the baud rate in the Arduino IDE to pretty much anything, so am I correct in guessing that the on board 16a2 has an autobaud routine in it?
What happens if the M2560 uses a CH340 instead?
I plan on changing the crystal on the board for the M2560 from 16Mhz to 7.3728Mhz and wiping the fuse settings to allow a wider Baud rate range with minimal error if it means anything
