The ESP32-WROOM-32UE is a WiFi + Bluetooth + BLE module based on the ESP32 SoC, featuring 4MB Flash memory and an IPEX (U.FL) external antenna connector.
Unlike the standard ESP32-WROOM-32 (which has an onboard PCB antenna), the 32UE version allows you to connect an external antenna for better signal range and stability.

Yes. The module supports:

• 2.4GHz WiFi (802.11 b/g/n)

• Bluetooth Classic

• Bluetooth Low Energy (BLE)

It can run WiFi and BLE simultaneously, making it ideal for IoT, smart home, and industrial applications.

The IPEX (U.FL) connector allows you to connect an external antenna, which provides:

• Improved signal strength

• Longer communication range

• Better performance inside enclosures

• More reliable connectivity in industrial environments

This makes it ideal for embedded systems placed inside metal or closed boxes.

The ESP32-WROOM-32UE comes with 4MB SPI Flash, which is sufficient for:

• OTA firmware updates

• Web server projects

• IoT dashboards

• MQTT applications

• BLE + WiFi combined applications

Yes, you can program it using:

• Arduino IDE

• ESP-IDF (official framework)

• PlatformIO

• MicroPython

It is fully compatible with the ESP32 development ecosystem.

This module is widely used in:

• IoT devices

• Smart home automation

• Industrial monitoring

• Wireless sensor networks

• GSM/WiFi gateways

• BLE data loggers

• Remote control systems
