6FT 3.3V TTL-232R Serial UART Cable with 3.5mm Audio Jack
This TTL-232R 3.3V converter cable is terminated by a standard 3.5mm Audio Jack (AJ) connector at one cable end. This is a TTL cable with an audio jack connector with +5V based TX and RX signalling.
1. USB TTL Serial Cable allows easy interfacing to devices over USB. The USB TTL Serial cable provide connectivity between USB and serial UART interfaces at 5V. 3.5mm audio jack input/output.
2. Connector configuration: tip-TxD,ring - RxD, sleeve- GND
3. Cable with audio jack connector with +5V based TxD and RxD signalling
4. Works in the same way as DB9 connector, however, the audio jack serves as a preparatory connection through hardware specifically designed to use an audio jack for serial communication, the rings in the audio jack serve the signal instead of typical pins.
