SoC Capabilities

This section lists definitions of the ESP32-S3’s SoC hardware capabilities. These definitions are commonly used in IDF to control which hardware dependent features are supported and thus compiled into the binary.

备注

These defines are currently not considered to be part of the public API, and may be changed at any time.
