RS232 TTL Converters

Our converter cables provide two way RS232 serial communication signal conversion between the TTL output (such as a micro-controller board, like the Arduino) to and from a personal computer RS232 Serial COM port. This converter can be used on any micro-controller which has TTL serial communications that needs to be converted to RS232. We have also expanded our cables to include USB to TTL.

Our standard cables are equipped with female DB9 connectors but male variants are available. The female cables will plug directly into common RS232 ports. The cable converts the 0V and 5V TTL signal to the -12V and 12V RS232 serial signal.
