> 3 dayCheap, fast, Wi-Fi Arduino alternative. The only downside compared to other controllers is the limited number of general-purpose IO lines.

> 3 dayThis thing is amazing. Super affordable, and its a walk in the park getting it working using PlatformIO and a Macbook. Just plug it in with a USB cable, and flash it. I personally dont use LUA, and I didnt have to do any modifications to the board itself to flash Arduino code from PlatformIO. Theres no reason not to buy some of these. I prefer it to the Arduino UNO and similar, simply because of its footprint and the fact that it has built in wifi. I was able to stand up a wireless server/ web service in one night with very few lines of code thanks to ESP8266WiFi.h.

> 3 dayUpdate: They said they would refund soon, Im waiting... NOPE. They wanted me to change my review first. DOUBLE NOPE. Refunded through Amazons A-to-z guarantee program. I love Amazon. Wifi did not work. TERRIBLE construction, see attached image. I was offered a software download instead of refund or replacement. I purchased this module from another manufacturer and it worked perfectly.

> 3 dayFollowing the directions in the Product description, I had little trouble getting the board to work with the Arduino IDE, to blink the LED, and to connect to my WiFi network. Worked like a charm. I did forget my SSID was case sensitive, but I forget stuff... Inexpensive and easy to use, especially if you are familiar with using Ardunino. Im excited to try it out using Lua and microPython, but for actually getting some things done, Im mostly there. My big interest now is finding out how much range I have and sending some data to a database via the interwebs using a cellphone. Cool stuff.

> 3 dayNice board. Good for breadboarding and labs. I didnt want to mess with LUA or micro python - I just used the Arduino IDE which is c++ I believe. Also, I needed to try several micro USB cables before on worked apparently common issue. However, I would definitely not recommend it for permanently mounted battery powered use where deep sleep is used. During deep sleep it would use 9.5 mA of current. This would run down a 14650 battery in less than a week. I know there are ways to chop it up to make it use less by disabling chips and the UART but I thought it was too involved. Just use a wemos or other smaller board. The ideal thing for this is the esp01 version, but I couldnt solder that super tiny microprocessor GPIO16 lead properly so Im stuck with a larger 8266 model.
