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
