3.3 V signal levels work fine for communication, but care must be taken not to additionally connect an internal 3V3 voltage regulator, which is provided on some USB UART interfaces, to the console, since this will conflict with the console's own 3V5 voltage regulation and could damage the USB device and/or the console. On such interfaces, it should suffice to '''just connect Rx, Tx and GND'''. Even better would be to use a RS-232-to-TTL level shifter, which can take the 3V5 voltage as reference directly from the console itself. | 3.3 V signal levels work fine for communication, but care must be taken not to additionally connect an internal 3V3 voltage regulator, which is provided on some USB UART interfaces, to the console, since this will conflict with the console's own 3V5 voltage regulation and could damage the USB device and/or the console.
