Since ESP-IDF officially began supporting ESP32-C3 from version v4.3, and v4.4 has not yet been officially released at the time of writing this book, the version used in this book is v4.3.2, which is a revised version of v4.3. However, it is important to note that by the time you read this book, v4.4 or newer versions may already be available. When selecting a version, we recommend the following:
For entry-level developers, it is advisable to choose the stable v4.3 version or its revised version, which aligns with the example version used in this book.
For mass production purposes, it is recommended to use the latest stable version to to benefit from the most up-to-date technical support.
If you intend to experiment with new chips or explore new product features, please use the
masterbranch. The latest version contains all the latest features, but keep in mind that there may be known or unknown bugs present.
If the stable version being used does not include the desired new features and you wish to minimise the risks associated with the
masterbranch, consider using the corresponding release branch, such as the
release/v4.4branch. Espressif's GitHub repository will first create the
release/v4.4branch and subsequently release the stable v4.4 version based on a specific historical snapshot of this branch, after completing all feature development and testing.
