  • Drivers for Windows 10, 11, macOS and Linux enable quick setup
  • Suitable for router repair, Arduino programming and wireless module configuration

USB to TTL serial converter for 3.3V logic

The SMUGDESK 6ft cable uses a genuine FTDI FT232RNL chip to translate USB signals into 3.3V TTL levels. It targets electronics engineers and hobbyists who program MCUs, flash firmware or debug routers, Arduino boards and wireless modules. The fixed 3.3V output matches logic-level devices directly without extra level-shifting circuitry.

Six-foot flexible lead

A 6ft cable provides reach across a bench while the standard 6Pin terminal header plugs into target boards. Built-in power, TX and RX LEDs blink to show live data flow and power presence during bring-up. Official FTDI drivers install on Windows 10, 11, macOS and mainstream Linux so the host PC recognises the virtual COM port immediately.

Stable conversion during long debug sessions

The authentic FT232RNL avoids the drop-outs common with counterfeit chips, keeping the UART link steady through extended flashing or monitoring tasks. Continuous 3.3V supply from the USB port powers small target modules without a separate bench supply. LED feedback lets you confirm traffic at a glance instead of probing pins while the session runs.

Questions about this item

How long is the cable for reaching a target board on the bench?

The cable is six feet long, giving plenty of slack for a desktop setup.

Does the cable show when data is actually moving?

Built-in TX and RX LEDs blink to indicate real-time transmit and receive activity.

What voltage logic level does the 6-pin header provide?

The header supplies a fixed 3.3 V output that matches 3.3 V logic MCUs and modules.
