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.
