SparkFun FTDI Starter Kit - 3.3V

Get everything you need to start programming 3.3V Arduinos in one package. This kit combines our reliable SparkFun FTDI Basic Breakout (3.3V) with the necessary USB Mini-B cable, so you aren't left searching for a cord when your project arrives! It is the perfect starter set for working with a 3.3V Arduino Pro Mini, Arduino Pro, and other custom 3.3V boards.

Data Terminal Ready

The included breakout board features the Data Terminal Ready (DTR) pin. Unlike standard FTDI cables that break out the RTS pin, our board breaks out the DTR pin. This allows the FTDI Basic to automatically reset your Arduino when a new sketch is downloaded.

• Why does this matter? You don't have to time a "reset button press" perfectly every time you upload code. Just hit "Upload" in the Arduino IDE, and the board handles the rest.

Visual Debugging & Connectivity

Troubleshooting serial connections can be a pain when you can't see what's happening. The board includes TX and RX LEDs so you can actually see the serial traffic. This visual confirmation is incredibly helpful for verifying that your board is talking to your computer.

• Voltage: The board ships configured for 3.3V operation (both power and logic).
• USB Cable: We've included a high-quality 6-foot USB 2.0 Type A-to-Mini-B cable, a perfect match for the connector on the board.

Easy Alignment

To prevent plugging it in backwards, we've labelled the pins BLK (Black) and GRN (Green) to match the standard coloured wires on FTDI cables and the silk screen on Arduino Pro and LilyPad boards. Just match the labels, and you are good to go.
