FT232BL 6Pin USB to TTL Serial Adapter, USB2.0 RS232 UART Converter Alternative to FT232RL, 3.3V/5V Switchable Debug Cable for Arduino, ESP32, STM32, Raspberry Pi

This 6Pin USB to TTL serial adapter is equipped with original FT232BL chip, serving as an excellent and economical alternative to the common FT232RL serial module. It efficiently completes bidirectional signal conversion between USB 2.0 interface and TTL UART / RS232 serial signals. A configurable voltage jumper is reserved on the board, allowing users to freely switch between 3.3V and 5V logic voltage levels, which effectively prevents low-voltage MCU and sensitive electronic components from overvoltage burnout.

Designed with intuitive TX and RX status indicator LEDs, the module lets you visually observe real-time data sending and receiving status during debugging. It supports an extensive baud rate from 300 baud up to 3Mbps, meeting diverse requirements of serial communication projects. The standard 6-pin pin header layout is convenient for quick wiring, plug-and-play after driver installation.

The adapter boasts outstanding cross-platform compatibility. It works seamlessly with Arduino, ESP32, ESP8266, STM32, Raspberry Pi, AVR, PIC microcontrollers, GPS positioning modules, RFID modules and various serial sensors. Drivers are available for Windows, macOS and Linux operating systems. It is widely adopted for embedded firmware flashing, serial log capture, circuit testing, device parameter configuration, electronic DIY projects, student laboratory experiments and industrial equipment maintenance.
