Introduction

Need high-speed, low-power Wi-Fi for IoT gateways, touch interfaces, or multimedia projects? The ESP32-S2-WROVER delivers 240MHz performance, 4MB flash, and 2MB PSRAM—ideal for demanding embedded applications.


Ultra-Fast 240MHz Xtensa LX7 Core

Built with a single-core 32-bit LX7 CPU, enabling real-time processing for audio, video, and sensor applications.


Enhanced Memory (4MB Flash + 2MB PSRAM)

Offers ample storage and fast data buffering, perfect for complex firmware and multimedia streaming.


Rich Peripheral Support (USB OTG, Touch Sensors, PWM)

Includes 43 GPIOs, USB OTG, touch sensors, and LCD/camera interfaces for versatile IoT development.


Low-Power Wi-Fi for Battery-Powered Devices

Supports 802.11 b/g/n (150Mbps) with dynamic voltage scaling for energy-efficient wireless connectivity.

Note: This module is recommended for developers currently. The peripheral circuit needs to be soldered when using it, and few peripheral interfaces may not perform the full functionality of the sample code. There are still bugs that have to be found and fixed.
