Product Information

Product Description

ESP32-WROOM-32E is a powerful Wi-Fi+BT+BLE MCU module that targets a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks such as voice encoding, music streaming and MP3 decoding.

ESP32-WROOM-32E integrates the ESP32-D0WD-V3 chip which has higher stability and safety performance. 

The integration of Bluetooth®, Bluetooth LE and Wi-Fi ensures a wide range of applications can be targeted.

  • Wi-Fi allows a large physical range and direct connection to the Internet through a Wi-Fi router
  • Bluetooth allows the user to conveniently connect to the phone or broadcast low energy beacons for its detection.


The sleep current of the ESP32-D0WD-V3 chip is less than 5μA, making it suitable for battery powered and wearable electronics applications.

This module offers industry-leading specifications and the best performance for electronic integration, range, power consumption, and connectivity. This performance is possible with a data rate of up to 150 Mbps and 20 dBm output power at the antenna which ensures the widest physical range. 

The operating system is freeRTOS with LwIP; TLS 1.2 with hardware acceleration built-in.

ESP32-WROOM-32E comes with a PCB antenna and external SPI flash.
