ESP32 DevKitC Development Board - WROOM-32D / WROOM-32U
The ESP32 DevKitC Development Board is a compact WiFi and Bluetooth development board for IoT, automation, robotics, sensor systems, and wireless control projects. It uses the ESP32-WROOM module and gives makers an easy way to program and test ESP32 projects through a USB connection.
This board is available in WROOM-32D and WROOM-32U styles. The WROOM-32D version has an onboard PCB antenna for general WiFi and Bluetooth projects. The WROOM-32U version has an external antenna connector, making it useful for builds that need better antenna placement or improved wireless range.
Available Styles
| WROOM-32D | ESP32 module with onboard PCB antenna. Best for general IoT and wireless projects. |
|---|---|
| WROOM-32U | ESP32 module with external antenna connector. Best for projects that need an external antenna. |

Setup Notes
Connect the board to your computer using a compatible USB cable. Install ESP32 board support in Arduino IDE or use ESP-IDF for development. Select the correct ESP32 board and COM port before uploading code.
For WROOM-32U, connect a suitable external antenna before testing WiFi or Bluetooth. For WROOM-32D, the onboard antenna can be used for normal wireless projects.
Important Notes
- Choose WROOM-32D if you want the onboard antenna version.
- Choose WROOM-32U if your project needs an external antenna.
- Do not connect 5V signals directly to 3.3V GPIO pins.
- Use a stable power source for WiFi and Bluetooth projects.
- Check pin labels before connecting sensors or modules.
- External antenna is not included unless stated in the package.
