Review on KEYESTUDIO Esp8266 Module Arduino Projects by Adam Hardy

There is no documentation for this product. When I scoured the internet looking for information, I found incorrect schematics and drivers that didn't apply. I found a driver, WiFiEsp, that actually builds, but I have yet to get it working. I need to listen on a socket and have found problems in the driver so far, but it's still not debugged and not working. If you plan to use them, be prepared to do a lot of digging to find the right information and source code. Additional Note: After working on it for a few days, I decided to give up the libraries. This device is programmed with the full TCP/IP stack and responds to Hayes-style AT commands. Now it works without libraries. It works as advertised and works great for my project.
