Ruth's sister USB TTL FTDI to 2.5 mm stereo audio cable

SKU CH-XDYN-ETJKR

Connects a USB TTL FTDI device to a 2.5 mm stereo audio jack for serial communication

  • USB-to-serial adapter enables direct device debugging
  • 5 mm stereo jack fits compact UART headers
  • FTDI chipset provides reliable 5 V TTL signalling
  • Plug-and-play cable simplifies embedded development

USB TTL FTDI to 2.5 mm adapter

This cable converts a USB FTDI serial interface to a 2.5 mm stereo audio jack for 5 V UART TTL communication. It suits developers and hobbyists who need a simple wired link between a PC and embedded hardware such as routers, microcontrollers or diagnostic ports.

Sustained data transfer behaviour

The FTDI chipset maintains stable serial throughput during long debugging or firmware-update sessions without the drop-outs seen in cheaper converter cables. It is not suited for buyers who require galvanic isolation or voltage-level translation beyond the fixed 5 V TTL signalling.

Questions about this item

Does the USB FTDI adapter draw enough current from the port to run continuously without overheating?

The cable is powered directly from the USB port at 5 V, so it only draws the small current the FTDI chip requires and runs cool during all-day use.

What device must already have a 2.5 mm stereo jack for this cable to connect?

The 2.5 mm plug fits equipment such as certain routers, switches or microcontroller boards that expose a UART console on a mini audio jack.
