Ruth's sister 3.3 V TTL UART serial cable 6 way 2.54 mm 1.8 m

SKU CH-FA3J-NS389

USB cable converts to 3.3 V TTL UART with a six-way 2.54 mm connector over 1.8 m

  • FTDI chipset enables reliable USB-to-serial conversion
  • 3 V TTL levels protect 3.3 V logic targets
  • 6-way 2.54 mm connector fits standard 0.1" headers
  • 8 m cable length gives flexible bench placement

Ruth's sister 3.3 V TTL UART serial cable

This new cable provides a direct USB link to 3.3 V logic serial ports using an FTDI bridge. The six-way connector uses a 2.54 mm pitch and the lead runs 1.8 m. It suits developers and engineers debugging embedded boards, routers or microcontroller projects that expose a TTL-level UART header.

Upgrading from bare wires

The fixed 3.3 V output replaces improvised level-shifter circuits and removes the risk of damaging 3.3 V targets with 5 V signals. The FTDI chipset also replaces generic CDC devices that need extra driver effort on some operating systems. The jump is worth it when a reliable, driver-supported bridge is required for daily development or field service work.

Questions about this item

What pin pitch and connector width does the 6-way header use?

The cable terminates in a 6-way connector with .1 inch pitch, matching a standard 2.54 mm header.

Which driver must be installed before the cable appears as a COM port?

Install the FTDI VCP driver for the TTL-232R-3V3-WE compatible chip; without it the USB link will not enumerate.
