Introduction

ESP32-S3-WROOM-2 is a powerful, general-purpose Wi-Fi + Bluetooth LE MCU module with rich peripherals. It provides acceleration for neural network computing and signal processing workloads, making it ideal for a wide range of AI and AIoT applications such as wake word detection, voice command recognition, face detection and recognition, smart home, smart appliances, smart control panels, smart speakers, and more. The module integrates an ESP32-S3R8V or ESP32-S3R16V SoC, with module variants available in 16/32 MB flash and 8/16 MB PSRAM. When PSRAM ECC is enabled, the maximum ambient temperature of the module can be raised to 85°C, but the available PSRAM size will be reduced by 1/16. The module core is based on the ESP32-S3 series SoC — an Xtensa 32-bit LX7 CPU with a maximum operating frequency of up to 240 MHz. The CPU can also be powered down while a low-power coprocessor continuously monitors peripherals for changes or threshold crossings.
