USB-UART Module FT232RL (FTDI) with 3.3V / 5V Switch for Flashing and Debugging

This compact USB-UART module, based on the FT232RL (FTDI) chip, is designed to connect microcontrollers and other electronic devices to a PC via USB. The board provides stable data exchange over the UART serial protocol and supports auto-reset when flashing boards such as the Arduino Pro Mini, thanks to the DTR pin. With the built-in jumper, you can select the logic level (3.3 V or 5 V) in one click. Features: Product type: hardware USB-to-TTL UART interface adapter module based on the FT232RL chip. Specifications: operating voltage switch (3.3 V / 5 V) via jumper, Mini-USB connector, data transmission indicators (RX/TX), DTR/RTS/CTS pins. Applications: flashing microcontrollers (Arduino Pro Mini, ESP8266, STM32) and debugging electronics via UART.
