Tiny, impressive, inexpensive wifi boards. Penny for size.

Tiny, impressive, inexpensive wifi boards. Penny for size.
This is my first time buying anything like this. I'm doing a small project involving an 8x8 LED matrix and running a server on the ESP8266. There are lots of code examples on the internet. I have already successfully connected to my local wifi. It is nice that this comes with 3 boards even though I'm not using all of them because I'm a beginner and could potentially screw something up. Also, the cost is surprisingly low considering what these can do.Here are the steps I took to get this thing up and running:- Download and install Arduino IDE (running it on Mac OS Catalina)- Download and install the driver (Please see the back of the dev board which specifies the correct driver to download. Just Google search for it).- Download the ESP8266 board library- Plug in the ESP8266 via micro USB (this provides the 3v power required. No other power source needed).- Write code and compile/upload it via the Arduino IDE. Note: I ran into an issue where python3 was not found during compile time. I had to install it via homebrew and even then I was still having issues. I recommend googling troubleshooting steps if you have this issue. I eventually resolved the issue by adding something to my bash_profile.- The code you upload will instantly execute as soon as the upload is finished. Anything you place in setup() will run once before anything else runs. Anything in loop() will keep executing over and over after setup runs. This is the common pattern for Arduino boards.Recommendation: Get a breadboard and some jumper wires which makes it much easier to connect components to the ESP8266.

5.0 out of 5 stars Great Board, make sure to use the right USB cable
Reviewed in the United States on February 22, 2021
These boards all worked excellently, once I found a micro USB cord that has the data wires connected. Can't stress enough that whether you buy this board or another similar one, you need a 4 wire micro-USB cord to flash it with. Check the end (see pic) to make sure it even has 4 wires (pictured one only has two). Even it does have all 4, they may not actually be connected to the other end (had this happen with one of mine). If in doubt, these are the wires I bought and they work: https://www.amazon.com/gp/product/B077ZWC2BR/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
I have 6 of these now running ESPhome and being used with sound, touch, and RIFD sensors. All are working well with no issues.

5.0 out of 5 stars Everything works great, but there's zero documentation
Reviewed in Canada on July 16, 2023
There are no manuals, no drivers, no links, not even a pinout. In the Arduino IDE you must select NodeMCU 1.0 ESP-12E module. The pinout matches the NodeMCU ESP-12E pinout.

After that, everything is a breeze. Everything works, wifi works, pins work (although there are fewer actually usable pins than you think, look into NodeMCU pinout to be sure you know what you are getting). A+ product.
