5. Set up your chip as:
Tools -> Board -> NodeMCU 1.0 (ESP-12E Module)
Tools -> Flash Size -> 4M (3M SPIFFS)
Tools -> CPU Frequency -> 80 Mhz
Tools -> Upload Speed -> 921600
Tools-->Port--> (whatever it is)
6. Download and run the 32 bit flasher exe at Github(Search for nodemcu/nodemcu-flasher/tree/master/ at Github) github.com
/nodemcu/nodemcu-flasher/tree/master/Win32/Release Or download and run the 64 bit flasher exe at: github.com/nodemcu/nodemcu-flasher/tree/master/Win64/Release
7. In Ar duino IDE, look for the old fashioned Blink program. Load, compile and upload
8. Go to FILE> EXAMPLES> ESP8266> BLINK, it will start blinking. Item-type: Electronics › Computers & Accessories› Networking Products › Network Transceivers

Although I haven’t done extensive testing with the boards yet, I did verify that both are functional. They came with the NodeMCU “AT” firmware loaded, but I use them with the Arduino environment and load ‘sketches’ to them. There is no documentation provided with the boards, but I think that most of the buyers of these boards are pretty adept at finding documents on the internet.
Using Windows 10 Home edition, the Silicon Labs CP210x USB driver loaded automatically. I think Win10 downloaded the driver from the internet because the search & loading process took about 60 seconds. Once the driver is loaded, connection time to the PC is nearly immediate upon plugging into the USB port. A little experimentation with different micro-USB cables confirmed that cable length does matter. Although the module receives power and will function on a longer cable, getting the device recognized as a COM device with a cable longer than 3-feet (1 meter) is not reliable. Some of my 6-foot cables worked, and some did not. I recommend cables of 3-ft or less for programming and debugging.
I only tested the COM port speed at 115.2Kbps and 230.4Kbps; both worked fine. I did not try to load sketches faster than 115.2Kbps.
I was not finding any information on which “board” to select in the Arduino environment, so I chose “NodeMCU 1.0 (ESP-12E Module)” and it seems to work perfectly.
After loading programs that generate web pages to control I/O pins, both boards connected quickly with my home network. In addition to securely connecting to my home network, I also have the boards set to simultaneously act as Wi-Fi “access points”. The default access point name is “AI-THINKER_” followed by the last six characters of the device’s MAC address. If you let your PC connect to it, the module will provide your PC with an IP address (yep, these things have onboard DHCP service) and you can access your web page(s) by pointing your web browser to 192.168.4.1. I have not looked into whether the access point name or IP are changeable, but the IP settings for the module’s connection to my home network are easily changeable.
One of things that I especially like about these particular boards is that all of the pins are clearly labeled on both sides of the circuit board. This makes prototyping much easier as you are not constantly looking at a pinout diagram and then counting pins on the board to make sure you are wiring to the correct pin. I like that the board has “FLASH” and “RST” buttons, and they are clearly labeled. All labeling is silk screened onto the circuit board, and appears to be quite durable.
For those who have not used ESP-12E modules, there is a blue LED next to the antenna on the actual ESP-12E. This LED is primarily there as an indicator that the board is communicating serially with the PC, so you should see it flashing when you are downloading a program or using serial communication with the board. This LED is actually connected to GPIO2, so if you configure that pin to be an output then you can also turn the LED ‘ON’ and ‘OFF’ with your program. It is a great way to flash status codes from your prototype program.
I know this review is long, but it is the type of information I look for when deciding whether or not to buy something I am considering buying.
Pros: Once I figured out how to flash from the Arduino to the ESP8266, it worked great in exactly that way; using the Arduino IDE to write and flash code just works. If you are looking for an ESP8266 to only use with Arduino, I can recommend this module as one of the best-priced options out there.
Cons:
1. Poor documentation. Had to read through the reviews to find out how to flash it.
2. Does not seem to work with Micropython. I found quite a few resources on how to flash micropython onto an ESP8266 and tried multiple times in multiple ways with multiple versions of micropython, but it just doesn't work. At best, I got the python prompt to show up a few times in my putty serial connection, but it was frozen (Windows bash "sudo screen..." only showed a blank screen with a cursor).
3. Seriously, documentation. As a person who is brand new to microcontrollers outside of the Arduino Uno and the Raspberry Pi 3, I didn't even know how much storage was on the thing.
Verdict: I will definitely keep these to play around with, but I'm probably going to find a different ESP8266 to use for my home automation projects. I will pay the premium to use python. If any of you have had success running micropython on these, feel free to link me to whatever instructions you used, because, at this price, I would love to use these instead of paying twice as much for something branded.
I just got to my relatives' house and started helping set up the projects I sent. The first one I worked with kept resetting for no apparent reason. After checking voltages in various places my conclusion is that the on-board voltage regulator was providing insufficient voltage to the ESP8266 chip. So I swapped out the first one with the second one to see if it would work. As soon as I provided power to it (in the exact same way as the previous one) a capacitor blew.
Only two of the five of these boards that I've used have worked as expected. I would avoid buying this board from this seller.
One other thing to note: these boards apparently can only handle 10V input according to the back side of the breakout board, not the more standard 20V you'll find as the max online for NodeMCU boards.
UPDATE: Adding a star because MakerFocus has some pretty great customer service. I've been contacted by them and they are sending me two replacement boards; apparently so far I've only used the "old version," not this new version that they are selling now. I will update this review again once I receive the replacements and can do some testing.
UPDATE 2: Makerfocus quickly sent me two replacement boards, both of the new version. I'm using these to build weather stations, so I simply upload the code and drop the new boards into the PCB. So far both are working like champs! Uploads worked fine and when I plugged the PCB into the wall neither board blew capacitors, so it's progress. Adding one star for functional boards and great customer service. I will change this to a full five stars once I'm able to test them over a longer period of time.
