ESP32-WROOM-32 Development Board | 38 Pins | Dual-Core WiFi & Bluetooth

Product Overview

The ESP32-WROOM-32 (38-Pin Version) from Pro Tronix is a powerful upgrade from the ESP8266 and standard Arduino boards. It features the ESP32-D0WDQ6 chip, which contains two independently controlled CPU cores. This allows one core to handle high-speed wireless connectivity while the other runs your complex application logic, preventing crashes and lag.

The 38-pin layout is the “expanded” version of the ESP32, breaking out more GPIOs than the smaller 30-pin variants. It includes built-in Hall effect sensors, capacitive touch sensors, and a massive array of peripheral interfaces like SD card support, high-speed SPI, and hardware UARTs. It is the gold standard for modern DIY IoT development.

Technical Specifications

Key Features

• Dual-Core Processing: Distribute tasks between two cores for a smoother, faster, and more reliable user experience.

• Hybrid Wireless: Support for both standard WiFi and dual-mode Bluetooth (Classic for audio/data and BLE for low-energy sensors).

• Maximum Pin Access: The 38-pin configuration provides more accessible ground and power pins, along with extra GPIOs for complex wiring.

• Ultra-Low Power: Includes several power-saving modes; in “Deep Sleep,” the chip consumes as little as 10µA, making it ideal for battery-operated devices.

• Integrated Sensors: Built-in touch-sensitive pins allow you to create touch interfaces without extra hardware buttons.

Common Applications

• Smart Home Hubs: Creating a central server to control lights, locks, and appliances via a web dashboard.

• IP Cameras: Handling low-resolution video streaming or image capture for security.

• Industrial Automation: Interfacing with a wide variety of industrial sensors via I2C, SPI, or CAN bus.

• Audio Streaming: Utilizing the dual-core power and I2S interface for internet radio or walkie-talkie projects.

⚠️ Logic Voltage Warning: The ESP32 operates at 3.3V logic. Connecting 5V signals directly to the GPIO pins can damage the chip. Use a Logic Level Converter when interfacing with 5V sensors.
