Greater than one weekI had a project that I wanted to use WiFi for (IoT), and also wanted to keep the controller as small as possible. The width of the board is a bit of a pain on a small breadboard (only 1 pin left to plug in after board is mounted). However, it is my understanding that this is the overall reference design, so I dont blame this seller for it. I ended up pairing this with a multiplexer to get enough analog in channels. This unit worked great and has way more memory that the Arduino that I was working with originally had. Im not worried about memory usage for this project at all now! Great value for the price, it has worked very well. As was said by another reviewer: this will be my go-to controller from here out.

> 3 dayThis thing is awesome, totally exceeded my expectations. For a fraction the price of an Arduino you get a wifi enabled board that can be used with the same Arduino IDE. It is a little tricky to get it flashed properly and setup with the Arduino IDE which is why I only gave it four stars. With a little googling there are tutorials that get you started.

> 3 dayI needed a ESP8266 Development Board for an open source project Im working on. This board fit the bill. Although the price is a little steep compared to other ecommerce websites, it work fine. Advice. Read the documentation and watch the YT videos to get a grasp on the possibilities. Hope this helps!

> 3 dayI was having problems getting serial output to work. It was just giving me garbage output. After contacting the seller, they suggested that I reflash the board and change some settings, which I did, and then serial output was fine. You can get the reflash by searching Gitbub for nodemcu-flasher. After reflash, make sure your IDE settings under the Tools menu are as follows: Board -> NodeMCU 1.0 (ESP-12E Module), Flash Size -> 4M (3M SPIFFS), CPU Frequency -> 80 Mhz, Upload Speed -> 921600. In your code and serial monitor, make sure to set them to the same speed.
