Overview

Product Overview

FT232RL USB to TTL serial cable adapter provides a direct way to connect a computer USB port to UART TTL serial devices for programming, console access, debugging, and data transfer. Built around the FT232RL chipset, this 6-pin cable exposes TX, RX, GND, and CTS/RTS hardware flow control for reliable communication with embedded hardware. It is well suited for Arduino Pro Mini, ESP32 or ESP8266 development, Raspberry Pi serial console work, GPS modules, routers, and other microcontroller or prototyping projects that need a simple USB-to-UART link.

Questions & answers

Frequently asked questions

It is designed for UART TTL serial devices, including Arduino Pro Mini, ESP32 or ESP8266 boards, Raspberry Pi serial console connections, GPS modules, routers, and other embedded hardware that uses a USB-to-UART link.
Connect the USB end to the computer and the 6-pin serial side to the target device’s UART pins. Match TX to RX, RX to TX, and connect GND; use CTS/RTS only when the device or software requires hardware flow control.
The cable uses an FT232RL USB-to-UART interface and exposes TX, RX, GND, CTS, and RTS lines. The product information does not specify the TTL logic voltage, so verify compatibility with the target device before connecting.
Yes. It provides a direct USB-to-TTL serial link for programming, console access, debugging, and data transfer with embedded boards and modules, making it useful for firmware uploads or serial monitor output when a board lacks onboard USB.
Check that the correct serial port is selected, TX and RX are crossed, GND is connected, and the target device uses compatible TTL serial levels. If communication is unreliable, enable CTS/RTS only when both sides are configured for hardware flow control.
