HiLetgo 2pcs ESP8266 NodeMCU CP2102 ESP-12E Development Board Open Source Serial Module (Pack of 2PCS)

but if you are making a project with this, you should expect to put in a little time to get it set up. Once configured, it programmed just fine over USB. Havent done much with it yet -- other paying jobs take precedence -- but the few things I tried worked just fine, Im confident I wont have much trouble with them.

This item works very well for the IoT. Im having no problems using the Arduino IDE to program it. The only negative is that it only has one analog input, but I knew that before buying.

Great product. Above expectation. Good price. Easy to program with ESPeasy or Arduino EDI.

This device works well if it is connected directly to a wireless router. But when connecting to a wireless access point ti had problems getting an IP from the DHCP server on the network. I had to add to the script static IP than it connected to the wireless access point. I am using mine to adjust the RTC in my Arduino Big LED Clock using NTP. The other thing i had an issue is if the access point looses power when the power is restored the device needs to be rebooted to connect. This may be able to be corrected in the script i am using. But i am new at programing and I used examples I found online. to build my clock

Ive used several of these NODEMCU board now (from several manufacturers) from several different vendors. The HiLetGo boards are by far the most reliable, with one serious caveat: They are the V2 versions of the NODEMCU, and have a different form factor than the newer V3 NODEMCU boards. (NODEMCU V3 boards are a few millimeters wider than V2 boards). This only matters if you intend to mount the board on a base-board (effectively, a breakout board)... all of the NODEMCU base-boards Ive seen are for V3 NODEMCUs. Form factor aside, Ive have great luck with the Hiletgo versions of these boards. Downloads at full speed always seem to work, and they never seem to barf with the dreaded espcomm sync failed error. If you have any Arduino skills, these are *great* boards. I (who have lots of programming experience, but close to zero web-coding experience) was able to use one of these boards as the brain of an internet-enabled, web-accessible garage door manager. I highly recommend the Hiletgo version of the NODEMCU boards. Hiletgo: if youre reading this, please release a NODEMCU V3 version of this board. :-)

Totally worth buying from this manufacture! I purchased 5 boards from them and all work effortlessly! One thing I recomend if your computer isn’t picking up the board, and you have the drivers already installed is to try and find another cable to connect to your computer. If you connect the board to your computer and it lights up and the computer doesn’t recognize anything but the board lights up with a blinking pattern , then it’s most likely that the cord your using is only supplying power to the board and not actually making a usb connection. I almost sent this product back thinking it was broken because of this. MAKE SURE YOU HAVE THE RIGHT TYPE OF CORD!!!!

Worked great for using along with a common PS4 project. Only turn it on when I need it so I cannot comment if it lasts running 24/7 but when I need it the device boots up quick. Very easy to use. No problems programming, I did choose a slower speed when writing to the device. Took about 30 minutes or so to write to it.

One board works perfectly. Had the other board break but hiletgo was quick to help replace the one that broke. Overall very pleased with the board

I just got two HiLetgo boards and they both work flawlessly. They came very well packaged and Im definitely pretty happy with it! If youre having trouble getting it to work on a Mac, Ive posted a step-by-step guide as the answer to one of the questions. I tried adding it to my review, but it doesnt go through (probably because it includes URLs).

I have been an Arduino project builder for the past five years and primarily worked with the Arduino Uno and Mega. Im constantly on the lookout for new projects to build. So when I recently found one that I was interested in, I learned that the project called for using an ESP8266, a device that I had never used before. I ordered this two-pack and they arrived quickly. After building the new project with it, I was impressed with how versatile these units are and that they are very easy to work with, so far as wiring and programming are concerned. The ability to connect one of these units to your Wifi allows you to stream all kinds of data into a project. The many things that you can do with one of these appears to be pretty limitless. Great tool and I highly recommend these to project builders.
