Product Information

Product Description


The ESP-WROVER-32B is an industry-leading combination Wi-Fi, Bluetooth (BT), and Bluetooth Low Energy (BLE) module designed around the ESP32-D0WD chip. With the on-board PCB antenna and 8MB Pseudo Static RAM (PSRAM) the device is capable of supporting a wide variety of applications.

Common applications include:

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

 

The module includes two (2) individually controlled CPU cores with adjustable clock frequency (80 MHz to 240 MHz). The CPU can be powered off while a separate low power co-processor constantly monitors the peripherals for changes in status.

Peripherals included in the ESP32-D0WD chip are:

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

The WROVER-32 utilizes a freeRTOS operating system with LwIP; TLS 1.2 and built-in hardware acceleration. It is fully-customizable with an open-source platform and secure encrypted over-the-air (OTA) updates, allowing firmware to be updated in deployed products with minimal expense.

GitHub provides a large collection of example code and information for device customizations.
