ESP32-S3-WROOM-1U-N4
Overview
The ESP32-S3-WROOM-1U-N4 is a powerful Wi-Fi and Bluetooth LE module based on the Espressif ESP32-S3 dual-core LX7 microprocessor. It features an integrated 4MB flash and 512KB SRAM, offering robust connectivity and processing capabilities for a wide range of embedded applications. This module comes without an integrated antenna, providing a U.FL connector for external antenna flexibility.
Why Choose This Part
This module offers a balance of performance and power efficiency with its dual-core 240MHz Xtensa LX7 processor and comprehensive peripheral set including USB 2.0 OTG. The U.FL connector for an external antenna provides design flexibility for optimizing RF performance and range. Its extensive range of low-power modes, down to 7uA in Deep-sleep, makes it well-suited for battery-powered applications.
