Product Information
Product Description
The ESP-WROOM-02D is a low-power Wi-Fi 802.11 b/g/n module with optimized RF performance and an internal PCB antenna. It’s low power consumption and compact size (18 x 20 x 3.2 mm) makes the device perfect for space restricted Internet of Things (IoT) applications.
Created around the ESP8266EX chip, the device offers a Tensilica L106 32-bit RISC processor and a maximum clock speed of 160 MHz. The integrated chip supports SPI flash memory with options of 2MB or 4MB.
80% of the processing power is available for development and customizations through the Real-Time Operating System (RTOS) and Wi-Fi stacks. A large collection of sample code and information is available on GitHub.
Common applications include:
- Internet of Things (IoT) solutions
- Home automation
- Industrial wireless control
- Wearable electronics
- Sensor networks
- Wi-Fi location-aware devices
