    Hello…

    Just got controllino mini and found that TXD(PD1) and RXD(PD0) on connector X1 are already used by internal USB-RS232 converter. Is it safe to use that pins on X1 connector when USB is disconnected?

    Hello,

    yes, it should be safe. Also Arduino boards have these signals accessible at the pinheader.

    Just be sure that you do not mix up the Serial communication from your sketch with the programming or communication through the USB.
