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!
