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.
