The ESP-WROVER-32-INT is a powerful combination Wi-Fi, Bluetooth (BT), and Bluetooth Low Energy (BLE) module designed around the ESP32-D0WDQ6 chip. It features up to 8 MB Pseudo Static RAM (PSRAM) that makes it particularly well suited for RAM intensive applications like:

  • Internet of Things (IoT) solutions
  • Wearable electronics
  • Home automation
  • Voice encoding
  • Music streaming
  • MP3 decoding
  • Sensor networks


Having a combination of Bluetooth, BLE, and Wi-Fi on board makes the module suitable for a variety of wireless networks, allowing for both Wi-Fi based internet connections and local BLE connections to a smart phone or tablet.

The WROVER-32 utilizes the freeRTOS operating system with LwIP and a built-in TLS 1.2 with hardware acceleration. It also offers secure, encrypted over-the-air (OTA) updates so that the module firmware can be updated remotely without manual or physical intervention. The system is completely open-source with a large collection of example code and information on GitHub.

The module has two CPU cores that can be individually controlled and a clock frequency that is adjustable from 80 MHz to 240 MHz. The ESP32 also has a sleep mode processor that allows for sleep current of less than 5 µA, making it suitable for battery powered applications.

The module also offers an easy process to gather sensor data or communicate with another microcontroller using a variety of peripherals, such as:

  • I²S
  • I²C
  • High-speed SPI
  • UART
  • Hall sensors
  • SD card interface
  • Ethernet
  • Capacitive touch sensors
