LinkNode D1 is Arduino-compatible WiFi development board which is powered by the high integrated WiFi chip ESP-8266EX. Thanks for the contribution from open source community who have developed Arduino core for ESP8266, this let Aduino IDE program LinkNode D1 without any change. At the same time, LinkNode D1 has Arduino-compatible pin out which make it very easy to connect to Arduino shield.
