  • I’m wondering if it is possible to use this board with a RS-232 interface. I know one option is going through an arduino board. But is there another way to do this? The RS-232 won’t be able to power the board but I was wondering of anybody has tried attaching an external power supply and still using the usb port.

    thank you
