The ESP32-S2-WROVER is a Wi-Fi MCU module built around the ESP32-S2 chip with 4 MB SPI flash and 2 MB PSRAM. The additional PSRAM makes it well suited for applications requiring larger data buffers, such as audio and video processing.

Based on the Xtensa single-core 32-bit LX7 CPU running at up to 240 MHz, the module offers a rich set of peripherals including SPI, I2S, UART, I2C, USB 1.1 OTG, ADC, DAC, capacitive touch sensor, camera interface, and LCD interface. It supports multiple low-power modes and includes hardware security features such as Secure Boot, Flash Encryption, and integrated AES/SHA/RSA.
