Board

The following files are firmware that should work on most ESP32-S3-based boards with 4MiB or more of flash, including WROOM and MINI modules.

This firmware supports configurations with and without SPIRAM (also known as PSRAM) and will auto-detect a connected SPIRAM chip at startup and allocate the MicroPython heap accordingly. However if your board has Octal SPIRAM, then use the "spiram-oct" variant.
