FT232RL USB to TTL 3.3V/5V FTDI Serial Adapter Module

FT232RL USB to TTL Serial Adapter Module is an essential tool for any electronics enthusiast or engineer working with microcontrollers and other embedded systems. This versatile module provides a reliable bridge between your computer’s USB port and a device’s TTL serial interface, making it perfect for programming boards like the Arduino Pro Mini, ESP8266, or other microcontrollers that lack a built-in USB port. Leveraging the powerful FTDI FT232RL chip, it ensures stable and fast data communication. You can easily switch between 3.3V and 5V logic levels, giving you the flexibility to work with a wide variety of hardware without needing an extra level shifter.

Key Features:

• Genuine FTDI FT232RL Chip: This module uses the authentic FTDI chip, providing excellent driver support for Windows, macOS, and Linux operating systems.
• Dual Voltage Support: A selectable jumper allows you to effortlessly switch between 3.3V and 5V logic levels, ensuring compatibility with a broad range of microcontrollers and sensors.
• Integrated Power LED: A built-in power indicator LED gives you a quick visual cue that the module is correctly powered on.
• TX/RX Status LEDs: Dedicated LEDs for transmit (TX) and receive (RX) provide real-time feedback, helping you quickly debug serial communication issues.
• DTR Pin: The DTR (Data Terminal Ready) pin is particularly useful for auto-resetting boards like the Arduino Pro Mini, streamlining your programming workflow.
• Compact and Robust Design: The module’s small form factor and standard pin header make it easy to use with breadboards or integrate into your final project.
