This Basic FT232RL USB to Serial Module with breadboard friendly pins features all of the pins needed for homebrew Arduino projects.
This module utilizes an FT232RL USB chip for maximum plug and play compatibility. It is easily recognized by modern operating systems without the need for special drivers.
All of the pins required by the Arduino bootloader are present at the breadboard friendly male header pins: RX, TX, CTS and DTR. There is a cut and bridge circuit trace jumper that can be used to configure the module for use with 3.3V or 5V projects. The jumper is wired for 5V projects by default.
This module comes in handy when building your own Arduino microcontroller and fits right into a standard breadboard for easy prototyping.
