Product Details

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.

Crystal Oscillator
2.6MHz
± 10 PPM

Interfaces
HSPI – connect to SPI Flash, display and MCU
PWM – control LED lights, buzzers, relays and electronics machines (4-8 channels)
IR – IR remote control after programming (38 kHz)
ADC – test power supply and input power voltages
I2C – connect to external sensors and displays
UART – communicate with UART devices
I2S – Collect, process and transmit audio data

ESP8266 SDK
Espressif ESP8266 SDK (Software Development Kit) is an IoT development platform. Within it you will find examples of applications including Smart Lights and Smart Plugs.
