ESP32 ESP‑WROOM‑32 Wi‑Fi & Bluetooth Dual‑Core Development Board

Versatile ESP32 development board based on the ESP‑WROOM‑32 module with dual‑core Wi‑Fi and Bluetooth, perfect for IoT, smart‑home, and connected device projects.

Compatibility

Works with the Arduino IDE using the official ESP32 Arduino core for easy sketch‑based development.
Fully supported by ESP‑IDF for professional, low‑level firmware development on the ESP32 platform.
Integrates smoothly with PlatformIO and other popular toolchains for embedded and IoT projects.
3.3 V logic is compatible with most modern sensors and modules, and it can interface with 5 V systems via level shifting when needed.

Key Features

• Based on the ESP‑WROOM‑32 module with dual‑core Tensilica Xtensa LX6 CPU, up to 240 MHz.

• Integrated 2.4 GHz Wi‑Fi (802.11 b/g/n) and Bluetooth Classic + BLE in a single chip.

• Typically includes 4 MB SPI flash, enough for complex applications and OTA updates.

• Rich peripherals: GPIO, UART, I²C, SPI, I²S, ADC, DAC, PWM, touch‑sensing pins, and more for flexible hardware interfacing.

• Onboard USB‑to‑serial converter and voltage regulator for simple power and programming from USB.

• Reset and boot buttons for easy firmware flashing and recovery.

• Breadboard‑friendly DevKit‑style form factor with dual rows of pins broken out.

Ideal Uses

• IoT and smart‑home devices such as sensors, switches, relays, and connected appliances using Wi‑Fi and/or Bluetooth.

• Wireless data loggers and monitors for environmental data, energy usage, or equipment status.

• BLE beacons, Bluetooth‑to‑Wi‑Fi bridges, and mobile‑connected gadgets that take advantage of dual radios.

• Learning and teaching embedded systems, networking, and cloud connectivity with a single, low‑cost board.

Safety Note

Use only within the specified voltage range and respect the 3.3 V logic level to avoid damaging the module or your peripherals. When experimenting with Wi‑Fi, Bluetooth, Zigbee, or Thread, follow local RF regulations and avoid enclosing the antenna in metal housings that can degrade signal quality. Always double‑check wiring before powering external sensors, motors, or relays from the board’s pins to prevent shorts or excessive current draw.
