About this board
Section titled “About this board”The reference ESP32-S3 devkit: dual-core Xtensa LX7 with vector instructions, generous RAM, and the widest pin map in the ESP32 side of the catalog. It is the board the S3 examples target, and the one to pick when a project needs more memory than the classic ESP32 has.
The S3 runs on its own in-browser engine, so a sketch that boots on hardware boots here with the same ROM log in the serial monitor.
