The external-antenna-connector variant of the ESP32-S3-WROOM-1 module family — same SoC and storage variants, RF interface through a connector instead of the PCB antenna. 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
- Same variant suffixes (N/R) and the same module-dependent GPIO 35–37 condition as the WROOM-1; the antenna difference affects RF wiring, not GPIO availability.
- 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.
