ESP-WROOM-02 is a 32-bit low power micro-controller (MCU) Wi-Fi Module that integrates TCP/IP network stacks and includes 10-bit ADC with HSPI, SDIO, UART, PWM, I2C, and I2S interfaces. 
The SPI flash is incredibly useful for storing user programs and firmware. 
In addition to the ESP8266EX chipset, the module also integrates an SPI flash with 32Mbits capacity, along with a SOP8-150mil package.
Features IEEE 802.11b/g/n at 2.4 GHz Integrated low power 32-bit MCU Integrated 10-bit ADC Integrated TCP/IP protocol stack Integrated TR switch, balun, LNA, power amplifier and matching network Integrated PLL, regulators, and power management units Various interfaces available, including SDIO, HSPI, UART, I2C, I2S, IR, PWM, GPIO, etc.
