ESP32-WROOM-32E-N16R2
Overview
The DFR1139 is an evaluation board featuring the ESP32-WROOM-32E-N16R2 module, a powerful dual-core Xtensa 32-bit LX6 microcontroller. It provides integrated 2.4GHz Wi-Fi and dual-mode Bluetooth (Classic and LE) connectivity with an on-board PCB trace antenna. This specific variant is equipped with 16MB of flash and 2MB of PSRAM, making it suitable for memory-intensive IoT applications.
Why Choose This Part
The module offers a high clock frequency of 240MHz and significant memory headroom with 16MB of flash, supporting complex firmware and Over-the-Air (OTA) updates. It maintains low power efficiency with a 5uA sleep current, while providing comprehensive peripheral support including hardware SPI, UART, and I2C controllers.
Applications
Key Specifications
Getting Started
Developers can use the Arduino IDE with the ESP32 core or the Espressif IoT Development Framework (ESP-IDF) for advanced C/C++ development. The board features a micro-USB interface for power and programming via a standard UART bridge, and it is compatible with standard 2.54mm pitch breadboards.
Also Consider
Arduino
- An alternative small-form-factor board that offers Wi-Fi and BLE connectivity within the standard Arduino ecosystem.
Espressif Systems
- A more cost-effective module variant with 4MB flash if 16MB is not required for the application.
