The SparkFun Pro Micro ESP32-C3 could be considered "plug and play", depending on the project. If you want to use any of the I/O pins, however, you'll need to solder something to the board. If you've never worked with castellated headers,we recommend checking out our Castellated Mounting Holes Tutorial for more information.

??? note "New to soldering?" If you have never soldered before or need a quick refresher, check out our How to Solder: Through-Hole Soldering guide.
