ESP8266 Nodemcu Wifi Development Board

Description:

The ESP8266 itself is a self-contained WiFi networking solution offering as a bridge from existing microcontroller to WiFi and is also capable of running self-contained applications.
This module comes with a built-in USB connector and a rich assortment of pin-outs. With a micro USB cable, you can connect NodeMCU devkit to your laptop and flash it without any trouble, just like Arduino.

More Specification:
• RAM: 32K + 80K.
• GPIOs: 17 (multiplexed with other functions).
• Analog to Digital: 1 input with 1024 step resolution.
• +19.5dBm output power in 802.11b mode
• 802.11 support: b/g/n.
• Maximum concurrent TCP connections: 5.

The most basic way to use the ESP8266 module is to use serial commands, as the chip is basically a WiFi/Serial
transceiver. However, this is not convenient. What we recommend is using the very cool Arduino ESP8266 project,
which is a modified version of the Arduino IDE that you need to install on your computer. This makes it very
convenient to use the ESP8266 chip as we will be using the well-known Arduino IDE.
