Keep it simple
The micro2440 board has 3 serials on boards and it has multiple USB-Ports which could be used with a converter. I think the minimal / normal usage is reading from 1 port. But for my solar plant there are 2 different manufacturers of inverters with different protocols. So I need at least 2 different threads for serial reading.
