ESP-WROOM-02 WiFi Module
The Espressif ESP-WROOM-02 is a low-power 32-bit MCU WiFi module. This small SMD module integrates the ESP8266EX WiFi chip and is designed for optimal RF performance. The ESP-WROOM-02 enables you to evaluate and further develop the device for you chosen application.
This module features a low-power mode. When operating at DTIM10 it will only consume 1.2 mW with WiFi connection. ESP-WROOM-02 operated with a frequency range of 2.4 GHz to 2.5 GHz.
Package
With a footprint of just 18 x 20 mm, the ESP-WROOM-02 is Ideal for integration into Compact devices, where space may be limited.
Memory
SPI Flash (16 Mb for storing programmes, data and firmware)
Internal SRAM and ROM
MCU
The on-board ESP8266EX device features the Tensilica L106 32-bit microcontroller and a 16-bit RSIC.
