FT232RL to UART TTL Converter

The FT232RL to UART TTL Converter provides reliable USB-to-serial communication using the FTDI FT232RL chip. It is the gold standard for programming Arduino Pro Mini, ESP modules, and any device requiring USB-to-TTL serial conversion.

Key Features

• FT232RL genuine IC for maximum compatibility
• USB to TTL UART conversion
• 3.3V and 5V selectable output
• Auto USB enumeration – no driver issues on most OS
• DTR and RTS pins for auto-reset during programming
• LED indicators for TX and RX activity
• Reliable and stable communication

Technical Specifications

Applications

• Arduino Pro Mini programming
• ESP8266/ESP32 flashing
• Serial debugging and monitoring
• GPS module configuration
• Serial device communication
• Legacy serial port replacement

Important Notes

• Select correct voltage (3.3V or 5V) before connecting target
• DTR pin used for auto-reset on Arduino Pro Mini
• FTDI drivers usually auto-install on modern OS
• CTS pin may need to be jumpered to RTS for some applications
• FT232 clones exist – genuine FTDI most reliable
