Product Descriptions

ESP32-S3-WROOM-2 is a powerful, generic Wi-Fi + Bluetooth LE MCU module that has a rich set of peripherals. It provides acceleration for neural network computing and signal processing workloads. It is an ideal choice for a wide variety of application scenarios related to AI and Artificial Intelligence of Things (AIoT), such as wake word detection and speech commands recognition, face detection and recognition, smart home, smart appliances, smart control panel, smart speaker, etc.

ESP32-S3-WROOM-2 comes with a PCB antenna. It has ESP32-S3R8V or ESP32-S3R16V SoC embedded. A selection of module variants are available for customers with flash memory of 16/32 MB and PSRAM memory of 8/16 MB. Please note that if the PSRAM ECC function is enabled, the maximum ambient temperature of the modules can be improved to 85 °C, while the usable size of PSRAM will be reduced by 1/16.
