Espressif’s generic Wi-Fi + BLE module built on the ESP32-S3, with an on-board PCB antenna and the storage variants listed below. 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 variant suffix encodes memory (N = flash, R = PSRAM). Whether GPIO 35–37 are occupied by internal flash/PSRAM communication depends on the variant — the decision table lives in the GPIO 35/36/37 guide. The module record below states the official condition verbatim.
- 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.
