1.2 Description
ESP32-S3-WROOM-1 and ESP32-S3-WROOM-1U are two powerful, generic Wi-Fi + Bluetooth LE MCU
modules that are built around the ESP32-S3 series of SoCs. On top of a rich set of peripherals, the acceleration
for neural network computing and signal processing workloads provided by the SoC make the modules an ideal
choice for a wide variety of application scenarios related to AI and Artificial Intelligence of Things (AIoT), such as
wake word detection, speech commands recognition, face detection and recognition, smart home, smart
appliances, smart control panel, smart speaker, etc.
ESP32-S3-WROOM-1 comes with a PCB antenna. ESP32-S3-WROOM-1U comes with an external antenna
