Low Cost (1,85€) USB to RS232 LVTTL Serial Cable

Low Cost (1,85€) USB to RS232 LVTTL Serial Cable

Hi there! Have you ever needed a USB to RS232 converter to connect to your microcontroller for serial communications? If you have, you probably bought a USB to RS232 converter and then used an external MAX232/DS232 to convert the RS232 voltage levels to TTL levels. That requires a little money, and a little work too.
