The ESP32-WROVER is a universal Wi-Fi+BT+BLE MCU module that is powerful and versatile for low-power sensor networks and extremely demanding tasks such as voice coding, audio streaming and MP3 decoding.
The ESP32-WROVER is the same as the ESP-WROOM-32 with the ESP32-D0WDQ6 chip*.
The difference is that the ESP32-WROVER module is additionally equipped with a 32-Mbit SPI PSRAM.
Thus, the ESP32-WROVER comes with both 4 MB SPI flash and 4 MB PSRAM.
The ESP32-WROVER uses a PCB onboard antenna, and the other module in the same series, the ESP32-WROVER-I, uses an IPEX antenna.
