ESP32-S3-WROOM-1-N4 WiFi Module (WiFi 6, 4MB Flash, PCB Antenna)

The ESP32-S3-WROOM-1-N4 is a high-performance wireless microcontroller module featuring WiFi 6 connectivity, 4MB onboard flash, and integrated USB OTG support. Designed for smart home systems, wireless sensor networks, and industrial automation, it is an ideal solution for hobbyists, engineering students, and commercial developers.

Dual-core processing and memory

Equipped with a 240MHz dual-core ESP32-S3 processor and 4MB of onboard flash, this module easily manages edge computing tasks and over-the-air firmware updates. Integrated WiFi 6 capability ensures stable, fast wireless performance in crowded RF environments.

Low-power operating modes

Dynamic voltage scaling and low-power RTC sleep modes significantly reduce energy consumption for battery-operated devices and wearables. The module can be awakened seamlessly via configurable GPIO triggers or capacitive touch inputs.

Native USB OTG and broad interfaces

Built-in USB OTG functionality allows direct host and device communication without external converter chips. With 42 accessible GPIOs, the module readily connects to SPI, I2C, display panels, and camera modules.

Clear pin layout and interfaces

The module breaks out essential power lines, ground connections, analogue inputs, and high-speed communications across a clearly structured footprint. Dedicated pins for UART and native USB data lines streamline programming and system integration.

Industrial-grade reliability

Tested for demanding deployment environments, the module operates across a broad temperature range of -40°C to 85°C. Full FCC, CE, and SRRC certifications ensure dependable compliance for commercial products and prototypes.
