HiLetgo 1PC ESP8266 NodeMCU CP2102 ESP-12E Development Board Open Source Serial Module Works Great for Arduino IDE/Micropython (Small)

This 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.

This is essentially a PROTOTYPE of a particle.io knockoff. 1. The driver source doesnt support any Linux kernel beyond 2.6.25 - WHICH WAS RELEASED NEARLY TEN YEARS AGO 2. Quality control is non-existent. Device never powered up and the ESD packaging was ESD in appearance only. 3. The Dev Kit repository is just a mess created by developers that dont understand how source control works or why bundling source files in binary containers is an incredibly stupid idea I gave up before I bothered to find a number 4. There are so many other better products that offer more features and stability at the same price. Avoid HiLetgo like the plague.

this is your all in one shop for making an internet controlled switch,weather station, twitter reader. 1/5 of the cost of other solutions. works w the arduino ide. a huge step up from the base ESP8266.

Easily configured under Arduino IDE, as described in sellers instructions, responsive and managed to upload template easily... so far no exact projects to use it in, but seems to be it will be easy to work with it... keeping order details, just in case Ill need to order some more... definitely will order from the same source...

So far so good! Its taken me a while to start working with it and I JUST figured out a big piece to the puzzle. I havent even tested this out thouroughly yet but other people NEED to know about this site which is a perfect tutorial to setting this up. USE THIS: [...] I will update if I run into any issues but that site saved me, BIG TIME.

works great! very useful little device! You just need to make sure proper USB cable, it should be Data cable not just power cable that is used for charging. I also hadt to use proper baud rate w/c is 115200 since 9600 wound work. Also make sure to install proper driver before you plug this to your pc/osx.

These ESP8266 are a great invention! Im using it everywhere for different IoT things at home.. I have this brand and another brand, they are quite similar, with small differences. They work fine both.

If you are familiar with the Arduino UNO then you will have no problems using this board.

I purchased a couple of these to use to run some NeoPixel LEDs, per the Christmas Tree article in the November 2017 issue of Nuts and Volts magazine. Though I have only so far hooked it up to the outermost ring of the NeoPixels, the software associated with the article works fine. What an amazing little device for such a tiny price.

Good board not alot of info. But item description and a quick google search help you set it up. Extra research and hard to read pin out were the reason for my 3 star review. You expect to load your code and test out but instead you have to take time out of your project to find a set up guide. After setting it up board works great ! Very fun to use connects to your wifi pretty quick, small!! 5v input 3.3v output good for my use on a relay board hooked up to 9 light bulbs!
