ESP32-WROVER-E
Wi-Fi + Bluetooth + BLE module on a PCB antenna with integrated SPI flash and PSRAM (module family offers N4R8, N8R8, N16R8, plus EOL N4R2 per the module datasheet).
ESP32-WROVER-E is Espressif’s module for the classic ESP32 SoC with integrated SPI flash and PSRAM on a PCB antenna. In MCUID’s hardware chain — chip → module → board — this page holds the module facts; chip capabilities live on the ESP32 chip page, headers and revisions on the DevKitC board page.
Start from the board: ESP32-DevKitC — see the first-flash guide for the bring-up path.
What the module decides
- GPIO 16/17 are occupied by PSRAM wiring on this module family — the module record below states the official condition; it matters whenever the module sits on an ESP32-DevKitC.
- Antenna and storage — the configuration above is this module’s fact; the chip page stays at silicon capabilities.
- Compatible boards — the list below is generated from the same data as the board pages.
