Description: This is the SparkFun USB to Serial Breakout for the FT232RL, a small board with a built in USB to serial UART interface. This little breakout is built around the FT232RL IC from FTDI, with an internal oscillator, EEPROM, and a 28-pin SSOP package this is a serious little chip.

With this version, we’ve corrected a few issues found with the board. These changes include fixes to the VCCIO, a change from the mini USB to micro USB connector, and a few footprint modifications. Other than finding this board much easier to use, it is still the same FT232RL breakout that you know and love!

Features:

  • Implements full v2.0 USB protocol
  • Needs no external crystal
  • Internal EEPROM for device ID and Product Description strings
  • Royalty-Free Driver support for Windows, Linux, and Mac OSX

  • I have to admit that instead of using these FTDI boards, I usually use a a Teensy 2.0 programmed as a USB to serial converter. Its a buck or so difference in price but then I can always build some smarts into the converter to suit my application.

  • I’d really like to see an FTDI alternative serial/usb board.

    After recent cluelessness by FTDI, I’m no longer comfortable with them as a source, and there seems to be a few other options available.

    • In their recent “Ask me anything” live session, I believe they mentioned they were going to make boards using Cypress’s offerings - but the time frame for these appearing here was weeks.

      • We are.

        The Cypress chips are really nice; they add some pretty advanced functionality beyond the normal serial functions, but retain pin-for-pin compatibility.

FT232RL Breakout Board is a good one!

This little breakout board came with everything needed to assemble in various configurations to fit your need. The board worked exactly as advertised, and was a snap to set up after assembly. Love the documentation provided at Sparkfun–best in class.


USB cable

Beware this does not use a standard USB mini cable. I needed to steal my wifes phone cable to fit.
