Best IOT Hardware: ESP-WROOM-02 an Affordable & Efficient Wi-Fi Module

There are many IOT wireless development boards out there but according to me & my work experience with Intel Edison, Arduino, Raspberry-pi, samsung artrik, bla bla bla but out of all i feel a 5$ 32-bit stand alone module is the best solution which works on 10microAmps only! Which makes it pretty cool.

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 module is highly integrated. It consumes extremely low power while providing wireless internet connection for embedded devices. It can be easily integrated into resource-limited devices due to its small form factor of only 18mm x 20mm.

Why i am trying to emphasis on that Esp module is clearly a fair tradeoff between performance, size and cost.
