FTDI USB to TTL UART 3.3V Logic Level Adapter Cable with a 6 pin header for TX, RX, GND, VCC(5V), CTS, RTS and a FeMale Socket Header. FTDI PCB Serial Module Inside Designed for broad compatibility with USB 2.0 type A hosts and reliable data transfer rates. Widely used in USB host environments to ensure dependable serial communication. FT232RL Chipset with EEPROM Configurability Chipset imported from the UK, mounted on the PCB board. Features configurable internal EEPROM. UART signals can be individually inverted by configuring the EEPROM, enabling flexible interfacing with diverse devices. Key benefits and strengths Function: Provides a reliable USB to TTL serial interface at 3.3V logic level, with a 6pin header for easy connection to microcontrollers and development boards. Compatibility: Works with USB 2.0 type A hosts and supports common UART needs across a wide range of boards and tools. Flexibility: EEPROMbased configuration allows UART signal inversion to accommodate boards with nonstandard serial signaling. Performance: Built around a FT232RL chipset to deliver stable, error serial data transfer. 23 practical use scenarios Microcontroller programming and debugging: Connect to Arduino, ESP8266/ESP32, STM32 and similar boards to flash firmware, monitor serial output, or issue commandline interfaces during development. PC serial communication and data logging: Use a terminal program on a PC to communicate with embedded devices, collect sensor data, or debug firmware behavior in real time. Firmware updates and bootloader access: Access bootloaders or recovery consoles on devices that require TTL UART at 3.3V levels for firmware updates and recovery procedures. Notes 3.3V logic level is supported for safe interfacing with lowvoltage microcontrollers. VCC pin provides 5V power when required by the target board. The setup uses a 6pin TX RX GND VCC(5V) CTS RTS configuration with a FeMale Socket Header for convenient connections.
