Hopefully a simple question...
Can I connect a USB cable to one of the 4 serial ports on an Arduino Mega?
I am using 2 of the 4 ports for Serial (using an RS232 converter) ports to communicate with a radio.
I want to use one of the other 2 ports to communicate with another type of radio that has a USB (MicroUSB type) connector.
Can I wire the Rx & Tx directly to the USB cable Rx & Tx or do I need some sort of converter?
