> 24 hourThese are great little modules. Great for the IoT or just messing with people. I have one loaded with a fake wireless access point that I can power all day from a small phone backup battery that RickRolls people when they join it.

> 24 hourGreat little board. Definitely recommend switching to the Arduino IDE though as youll get more bang for your buck with the minimal memory it has. Be sure to watch out for the pin usage... having certain voltages on the pins caused mine to not boot and put it into other modes. Otherwise great little board for the money!

> 24 hourI started with Arduino boards on some small projects, then I wanted to add WIFI capability to the projects. Initially I was trying to add wifi modules to Arduino, but I came across this ESP-12E board, and decided to give it a try. The package came with 3 boards, for about $14, very inexpensive in my opinion. I connected one to my Mac, and started trying the example sketches through Arduino IDE. This little board really surprised me with its capability, and it brought me many ways to expand my ideas on the projects, far exceeded what I had initially expected. I am in the middle of transfer all my projects from Arduino boards to this ESP-12E, and also on its successor ESP-32. I am very pleased with the purchase, and with many other components that I bought from HiLetgo. Finally, as some other reviewers have already pointed out, the CP210X USB driver needs to be installed (download at silabs dot com) on the host computer first, before Arduino IDE to be able to upload sketches to the board.

> 24 hourThese guys are cool! First ESP projects ive done. Used some with wled for kitchen light controller and some for my Christmas light display. Easy to flash easy to work with, hard not to get obsessed thinking what you want to build next.

> 24 hourThis worked great. Worked. Not so much now. There appears to be a soldering flaw on the board and it no longer communicates with the USB or several pins unless I hold my finger just right on the board. Other than this, I would strongly recommend it.

> 24 hourThis board is incredible. Its connectivity is lightning quick, it is programmed with the Arduino IDE and Syntax, and it has a built in USB Port all for a price lower than youd pay for any of that by itself. I built an app to control my TV with my Android phone using this board and an IR LED and Ive already bought a handful more of these for other things. Cant recommend enough and cant wait to use in future projects.
