USB-RS-232 (TTL level) converter for connecting serial interfaces (TTL level) to the PC via USB

This USB-to-RS-232 converter with TTL level is ideal for debugging purposes in microcontroller circuits. Since most controllers provide only TTL signals at the processor’s serial interfaces, this tool is perfectly suited for conveniently monitoring those signals on a PC or notebook. The galvanic isolation also provides a high level of protection for your processor board.
