The FT232RL USB to TTL Serial Adapter Module is a high-performance USB-to-UART interface board designed for programming microcontrollers, flashing firmware, and serial debugging. Built around the industry-standard FTDI FT232RL chip, it features selectable 3.3V and 5V logic levels, integrated RX/TX status LEDs, and a DTR pin for seamless automatic reset programming with Arduino Pro Mini, ESP8266, and STM32.
Description
Connect your microcontrollers directly to your computer’s USB port with the FT232RL USB to TTL Serial Adapter Module. Whether you are flashing firmware to an Arduino Pro Mini, configuring ESP8266/ESP32 Wi-Fi modules, reading serial telemetry, or debugging embedded code, this module provides rock-solid, high-speed serial communication.
Built using the reliable FTDI FT232RL IC, this module features an onboard jumper allowing you to switch instantly between 3.3V and 5.5V logic levels, making it safe for both 5V standard microcontrollers and sensitive 3.3V low-power chips. It includes standard pinouts—including the essential DTR pin—which enables automatic reset and hassle-free code uploading without manually pressing the reset button on target development boards.
