Arduino KIT
NodeMCU ESP8266 is developed based on ESP8266EX WiFi Chip inside ESP-12E Module to easily connect to WiFi with a few steps. The board also integrates IC CP2102, which makes it easy to communicate with the computer via Micro USB to operate the board. And there are available buttons, LEDs for easy learning and research. ESP8266 is widely used in IoT projects, ESP8266 Blynk.
With a small size, flexible board easily links with peripherals to form projects and prototypes quickly.
