An emerging popular WiFi shield ESP8266


It would be cool to see this shield supported:


It is supported, just not officially.

Follow my HowTo…


I think he means using it as a shield for the Arduino, which I believe is being worked on right now.


The Blynk library supports it. Don’t know if Cayenne does as I’ve not tried it myself.

It may be as simple as using this line instead in your arduino sketch:

#include “BlynkSimpleShieldEsp8266_HardSer.h”



Do a quick search in this community for esp8266


Bumping this old thread to share that we’ve just provided support in our MQTT Arduino library for using ESP8266 as a shield :slight_smile: We’ve done basic testing and works well. Give it a try for your project and let us know how it works out for you !

Here is the updated library on our github:
