Black USB-A plug to six-pin header cable with three status LEDs

SMUGDESK

SMUGDESK FT232RNL USB to TTL UART Debug Cable 3FT 5V 6-Pin

SKU CH-BAYH-PJTTR

Converts USB to 5V TTL UART with genuine FTDI FT232RNL chip, six-pin header, TX/RX/PWR LEDs and 3ft shielded cable for MCU programming and embedded debugging

  • Genuine FTDI FT232RNL chip ensures stable serial conversion with official drivers
  • 6-pin 2.54mm header provides 5V power, TX, RX, RTS, CTS for full hardware flow control
  • Built-in PWR, TX, RX LEDs give real-time visual feedback on data activity
  • 3-foot shielded PVC cable with moulded USB-A resists EMI and frequent plug cycles
  • Works on Windows 10/11 32/64-bit, macOS and Linux for MCU programming and debugging

Professional USB-UART Debug Cable

The SMUGDESK FT232RNL adapter converts a standard USB port into a 5V TTL serial interface using a genuine FTDI FT232RNL controller. It provides six pins on a 2.54mm header including power, ground, TX, RX, RTS and CTS with hardware flow control. Three onboard LEDs show power, transmit and receive activity in real time. The 3-foot shielded cable reduces EMI for reliable communication in lab or field environments.

Engineers and hobbyists flashing firmware

Developers who need a stable, driver-supported link for MCU programming, router recovery or industrial equipment maintenance will benefit from the authentic chip and wide OS support across Windows 10/11, macOS and Linux. Users whose target hardware requires 3V3 logic levels or isolated signals cannot use this fixed 5V output cable and must select a different converter.

Genuine FTDI FT232RNL chip

The original FT232RNL IC delivers official VCP and D2XX drivers that prevent the recognition failures common with clone silicon. This single component determines whether the adapter will enumerate reliably on every supported operating system without manual driver hunting.

Questions about this item

Does the FT232RNL chip itself wear out and need replacement after heavy use?

The genuine FTDI FT232RNL control IC is a solid-state component with no moving parts, so it does not wear out or require scheduled replacement under normal operation.

What limits continuous data throughput on this cable?

The hardware flow-control pins RTS and CTS manage the data stream, and the FT232RNL supports baud rates from 300 bps up to 3 Mbps, so the selected baud rate is the first practical limit.

How much heat or noise does the adapter produce when left running all day?

The cable draws power from the USB port to supply 5 V TTL output; the FT232RNL runs cool with no fan, and the status LEDs are the only visible activity, so heat and noise are negligible.
