The UNO Based ESP8266 Nodemcu Development Board in the form of the Arduino UNO board format. This WeMos D1 R1 board is compatible with the Arduino IDE and with NodeMCU.The board is controlled by the ESP8266 chip (a 32-Bit processor) and has a larger flash memory compared to an Arduino Uno. It consists of 11 digital I/O pins and 1 analog (input) pin. the board can be connected using a Micro-B type USB cable.

The ESP 01 or ESP8266 WiFi Module is a self-contained SOC. ESP8266 serial module has integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The esp8266 wifi module Arduino is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. Each ESP8266 module comes pre-programmed with an AT command set firmware, meaning, you can simply hook this up to your Arduino device and get about as much WiFi-ability as a WiFi Shield offers (and that’s just out of the box)! The esp 01 connect to wifi module is an extremely cost-effective board with a huge, and ever-growing, community.

The Latest ESP-12E ESP8266 Wifi Module AP & Station Remote Serial Wireless IoT Board is an integrated chip designed for the needs of a new connected world. It can handle all the necessary overhead for communicating with your network, such as TCP/IP stack and communicating with your 802.11 networks. It is completely addressable over SPI and UART protocols allowing you to connect your sensors or project directly to it through its GPIO’s. ESP8266 is a low-cost Wi-Fi chip with full TCP/IP stack and MCU (Micro Controller Unit) capability.
