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

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.

This WiFi development board is amazing! The prime delivert was fast and efficient so I got my product quickly which was nice, additionally the price of this development board is amazing considering all it can do! I would recommend buying this board for any Arduino project you may have.

I bought this to test wifi jamming LOLOLOLOLOL

The little device has the potential to bring the awesomeness of IoT to every home and device. This revolution will not be televised. It will be broadcast over WiFi. Cheers !

spend 3 days trying to get a win 10 driver to work to no avail - found countless people online with the same issue and no resolutions

Complete Game Changer!!! I ran into this product while searching for options for providing Wifi to an Arduino. Im currently using it to access my garage door remotely via a mobile app. Stable and easy to use. Plenty of tutorials out there on how to use it. Best part is you can still use the same arduino IDE to write the same code as arduino and upload to the board. Simply specify the board type (from arduino to NODEMCU) and done! I have sensors, relays and other devices connected to it and works without a hitch. Love the compact size and plenty of documentation out there for it. Give it a shot.

My go to esp rig. Ive tried the bare esp 8266 chips and had no success trying to solder them to various rigs. This is such a time saver as it has all the stuff I would have spent time rigging up already integrated.

Bought these twice. Total of 4. They keep dying with cant flash error that is unrecoverable. One unit got so hot to touch it was stinking the room. I do not recommend these.

One dead on arrival. Other one needed to remove pins from and tore all the pads very easily.

Using this to host the things needed to do things to the park.
