Resources and Going Further

The ESP8266 WiFi Shield is open source hardware, you can find all of our design documents in our ESP8266 WiFi Shield GitHub Repository. In addition to that, these resources may come in handy:

• ESP8266 WiFi Shield Schematic
• ESP8266 AT Command Set
• SparkFun ESP8266 AT Arduino Library

ESP8266 Resources

An awesome community has grown around the ESP8266. We owe them big time for the amazing Arduino addon they've cooperatively built. For all of your ESP8266 needs, we recommend checking out the esp8266.com Community Forum. In addition to that, here are a few ESP8266-related resources we've found incredibly helpful:

• ESP8266 GitHub User Repos -- Tons of incredible tools can be found here. From Crosstool (to compile your own Xtensa GCC, G++, etc.) to the ESP8266 Arduino GitHub Repo
• ESP8266 Community Wiki -- Related to the community forum, there's a good amount of information available in this wiki.
• NodeMCU Firmware and the NodeMCU Flasher -- NodeMCU is a popular firmware for the ESP8266. It implements a LUA-based interpreter on the ESP8266 MCU.
• Espressif Board Forums -- Espressif, the manufacturers of the ESP8266, have a forum of their own. You can sometimes find updated software development kit downloads, or other helpful links here.
• Espressif GitHub Repos -- Espressif is also somewhat active on GitHub. They host a couple versions of the SDK here.

The ESP8266 Thing is open source hardware! If you need, or just want to look at, the PCB design files, you can find them in our ESP8266 Thing GitHub repository.

Going Further

Need a little project inspiration, now that you've got your ESP8266 Thing up-and-running? Maybe some of these related SparkFun tutorials will help spur some ideas:

With it's deep sleep ability, the Thing is a great foundation for a WiFi-based weather station, or a friendly, huggable, interactive plushy.
