Description

The ESP32-WROOM-32E-N4 is Espressif’s production-ready wireless module, built around the ESP32-D0WD-V3 dual-core Xtensa LX6 microcontroller. It provides a fully certified RF solution with an integrated PCB antenna, simplifying FCC/CE compliance for end-products. The module balances processing performance with low-power states, enabling efficient Wi-Fi and BLE connectivity for always-on sensing and control applications.

Engineered for industrial-grade reliability, it operates across a -40°C to +65°C temperature range and supports secure boot and flash encryption for robust firmware security. Its comprehensive peripheral interface suite allows direct connection to displays, sensors, and industrial buses, making it a foundational component for smart home automation, industrial telemetry, wearable tech, and consumer electronics.

Key Features

  • Certified Wi-Fi 4 (802.11 b/g/n) and Bluetooth 5.0 Low Energy (BLE) module.
  • Integrated high-performance PCB antenna for simplified RF design.
  • Dual-core Xtensa LX6 processor with clock frequencies up to 240 MHz.
  • Advanced low-power modes for extended battery life in IoT deployments.
  • Hardware-accelerated cryptography (SHA, RSA, AES) for secure connections.
  • Wide operating voltage range (3.0V - 3.6V) compatible with LiPo and regulated supplies.
  • RoHS compliant construction for environmental safety standards.
  • Moisture Sensitivity Level (MSL) rated for proper handling during assembly.

Applications

Frequently Asked Questions

What development frameworks are compatible with the ESP32-WROOM-32E-N4 module?

The module is fully supported by Espressif's official ESP-IDF (IoT Development Framework) for advanced feature control and low-level programming. It is also widely compatible with the Arduino Core for ESP32 via the Arduino IDE, PlatformIO for VS Code, and MicroPython for rapid scripting. You can program it using a USB-to-Serial adapter connected to its UART (GPIO1/TXD, GPIO3/RXD) pins, following standard ESP32 flashing procedures involving GPIO0 and EN/RST pins.

How do I power the ESP32-WROOM-32E-N4 module in my project?

Supply a stable DC voltage between 3.0V and 3.6V to the VCC (3V3) and GND pins. The module can draw significant current peaks (up to 500mA) during RF transmission, so ensure your power regulator or battery can deliver at least 500mA continuous current. For battery operation, utilize the chip's deep sleep modes (consuming ~10µA) to extend life. Decoupling capacitors (e.g., 10µF and 100nF) placed close to the power pins are essential for stable operation and reducing noise.

Can I use an external antenna with this module instead of the integrated PCB antenna?

No, the ESP32-WROOM-32E-N4 variant is designed with a permanently integrated PCB antenna and does not feature an external antenna connector like an IPEX or SMA. The RF trace is internally matched to the onboard antenna. For designs requiring an external antenna, you would need to select a different module variant from Espressif, such as the ESP32-WROOM-32UE which includes an IPEX connector for attaching external antennas with higher gain.
