Espressif Systems ESP32-S3-WROOM-1/1U Modules

Espressif Systems ESP32-S3-WROOM-1/1U Modules are 2.4GHz Wi-Fi^® (802.11 b/g/n) and BLUETOOTH^® 5 (LE) modules built around ESP32S3 series of SoCs, Xtensa® dual-core 32bit LX7 microprocessor. The ESP32-S3-WROOM-1/1U provides acceleration for neural network computing and signal processing workloads. The ESP32-S3-WROOM-1/1U Modules feature flash up to 16MB, PSRAM up to 8MB, 36 GPIOs, and a rich set of peripherals. Additionally, the devices have an onboard PCB antenna (ESP32-S3-WROOM-1) or an external antenna connector (ESP32-S3-WROOM-1U).

The Espressif Systems ESP32-S3-WROOM-1/1U Modules are an ideal choice for a wide variety of application scenarios related to AI and Artificial Intelligence of Things (AIoT). These include wake word detection, speech command recognition, face detection and recognition, smart home, smart appliances, smart control panel, and smart speaker.
