Hi,
I am planning to pair two arduino pro minis together to send serial data to each other over RS232 (via MAX232s). Only problem is that I will be sending via a multiplexer which runs at 115200 baud. I've heard about people having problems with communicating this fast on a Pro Mini. Am I likely to have problems? I can use either 5v or 3.3v boards if that makes any difference...
Does anyone have any experience with this?
Thanks in advance
