SKU CH-VVYG-X8JF7

Converts USB to 3.3 V TTL serial using an FTDI chip and ends in a 3.5 mm stereo jack

  • FTDI chip provides reliable serial conversion
  • 3 V logic level suits low-voltage targets
  • 5 mm stereo jack simplifies board connection
  • 6-foot cable length gives flexible routing

USB to TTL serial adapter

This cable provides a USB to TTL serial converter using an FTDI chip operating at 3.3 volts. It terminates in a 3.5 mm stereo audio jack plug for connection to target hardware. The 6 foot length allows flexible placement inside or outside a chassis. It is intended for developers and engineers debugging embedded systems or configuring network equipment.

Integration into a build

The adapter draws power from the USB host and requires no external supply. It frees up a standard serial port on a PC or server by bridging to the 3.5 mm TTL interface. The stereo plug matches common debug headers on routers, switches and development boards. Buyers needing a different voltage level or a bare wire ending should select another model.

Highlights

Questions about this item

What voltage does the FTDI chip output on the TTL-232R-3V3-AJ?

The FTDI chip provides a 3.3 V TTL UART signal level on this cable.

Does the 3.5 mm stereo plug carry power that could heat up during all-day use?

The 3.5 mm jack carries only 3.3 V TTL data lines; no significant power is delivered, so heat buildup is negligible.
