## Description

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. Note: This is a standalone module recommended for experienced developers. Peripheral circuitry must be soldered for use, and some peripheral interfaces may not fully support all sample code functionality. Key Features ESP32-S2 Processor – Xtensa single-core LX7 @ up to 240 MHz Wi-Fi – 802.11 b/g/n, up to 150 Mbps, 2412–2484 MHz 4 MB Flash + 2 MB PSRAM – Extended memory for data-intensive applications USB 1.1 OTG – Full-speed USB On-The-Go interface Low Power Modes – Fine-grained clock gating, dynamic voltage and frequency scaling, ULP coprocessor Hardware Security – eFuse, Secure Boot, Flash Encryption, Digital Signature, AES/SHA/RSA PCB Antenna – Integrated on-board antenna Specifications CPU: Xtensa single-core 32-bit LX7 @ up to 240 MHz ROM: 128 KB SRAM: 320 KB + 16 KB RTC SRAM Flash: 4 MB SPI PSRAM: 2 MB Wi-Fi: 802.11 b/g/n, up to 150 Mbps Interfaces: GPIO, SPI, UART, I2C, I2S, LCD, Camera, IR, LED PWM, USB 1.1, ADC, DAC, touch sensor, temperature sensor GPIO Count: 43 Crystal: 40 MHz oscillator Operating Voltage: 3.0–3.6 V Operating Temperature: −40 to 85 °C Dimensions: 18 × 31 × 3.3 mm Certifications: FCC, CE-RED, SRRC, RoHS/REACH Package Contents 1× ESP32-S2-WROVER Wi-Fi module (PCB antenna) Resources ESP32-S2-WROVER Datasheet ESP32-S2 Technical Reference Manual
