ESP32-S3-WROOM-2
ESP32-S3 module family with octal SPI flash and octal SPI PSRAM on a PCB antenna.
Espressif’s ESP32-S3 module family with octal SPI flash and octal SPI PSRAM. In MCUID’s hardware chain — chip → module → board — this page holds the module facts: variants, module-level pin conditions and board compatibility. Chip capabilities live on the ESP32-S3 chip page; headers, revisions and connectors on the board page.
Start from the board: ESP32-S3-DevKitC-1 — see the first-flash guide for the bring-up path.
What the module decides
- The official DevKitC-1 guide states the GPIO 35–37 occupation for this family without variant qualification — treat those pins as taken on boards fitted with this module, and check the GPIO 35/36/37 guide before planning to use them.
- Storage variants — the table below lists the official variants with their official source; flash/PSRAM capacity is this module’s fact, not the chip’s.
- Compatible boards — the list below is generated from the same data as the board pages.
