This product serves to connect a device with an RS232/UART interface to a USB port (USB1.1 or USB2.0). The converter can convert interfaces with RS232 level, TTL level (5 V) and 3.3 Volt level to USB.The circuit board of the converter is soldered in directly or via a socket strip. It is also possible to solder on a 9-pole Solder SubD plug and attach a USB cable to the other end of the board.If you do not solder on a 9-pole SubD plug, it is possible to break off the corresponding part of the circuit board at a predetermined breaking point to save space on the own application.This text is machine translated.
