# Fiddy - the FTDI Clip ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/037/439/medium800thumb/tools_Fiddy-2.jpg?1479795838) ## FTDI is Great! But header pins can get in the way of your next tiny project. For the benefits of FTDI, without the bulk of header pins, Fiddy comes to the rescue.
