Product Information

Product Description

Authorized North America Distributor Stamp

The ESP-WROVER-32-EXT module supports Wi-Fi, Bluetooth (BT), and Bluetooth Low Energy (BLE) connections making it suitable for a variety of wireless applications. Designed around the ESP32-D0WDQ6 chip it features an external U.FL (IPEX) connector and 4 MB Pseudo Static RAM (PSRAM).

The WROVER-32 runs on freeRTOS operating system with LwIP and a built-in TLS 1.2 with hardware acceleration. With the secure encrypted over-the-air (OTA) updates, firmware can be easily updated remotely without manual or physical intervention. The module supports open-source system allowing the device to be completely customized. Example code and information can be found at GitHub.

The device has two (2) individually controlled CPU cores with 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 WROVER-32 module also offers an easy process to gather sensor data or communicate with another microcontroller using a variety of peripherals, such as:

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

 

Common applications include:

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