LinkSprite LinkNode D1 Arduino-Compatible Wi-Fi® Development Board is powered by the highly integrated ESP-8266EX WiFi chip. The LinkNode D1 benefits from the contribution of the open source community who have developed Arduino core for ESP8266. This allows Aduino IDE to program LinkNode D1 without any change. LinkNode D1 has an Arduino-compatible pin-out which make it very easy to connect to Arduino shield.
