Product Information
Product Description
High Temperature option is NOT for new designs.
The Espressif ESP-WROOM-32D is an industry-leading Wi-Fi, Bluetooth (BT), and Bluetooth Low Energy (BLE) module designed around the ESP32-D0WD chip. This module offers a PCB antenna which increases the RF performance for a wider range of applications.
With the integration of the ESP32-D0WD chip, the device provides two (2) individually controlled and powered CPU cores. The CPU has an adjustable clock frequency (80 MHz to 240 MHz) and can be powered off while a separate low power co-processor continuously monitors the peripherals for changes in status.
Some of the powerful peripherals integrated within the ESP32-D0WD include:
- High speed SPI
- UART
- I²S
- I²C
- Ethernet
- SD card interface
- Hall sensors
- Capacitive touch sensors
- Low-noise sense amplifiers
The WROOM-32D 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.
Common applications include:
- Internet of Things (IoT) solutions
- Wearable electronics
- Home automation
- Music streaming
- MP3 decoding
- Sensor networks
- Voice encoding
