Wifi works well and easy to set up using the WifiManager library.
Consider this a huge step up from Arduino in terms of capacity and speed with the bonus of built in wifi.
Prefer that the pins not be soldered (drop a star). They are hard to remove and maybe one device gets stuck in a breadboard but real projects need wires soldered which means removing the pins.
Final thought: great for the price but given the number of ESP-32 devices now available for not more, I would probably pay a little extra for a much more powerful device.
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.

I have 6 of these now running ESPhome and being used with sound, touch, and RIFD sensors. All are working well with no issues.

It’s 4MB btw, didn’t see any mention of that on the product page. After that install with the latest full size micropython firmware was a breeze
1. Use a motion sensor to automatically turn my desk fan on and off when I sit down or leave my desk area. That project used NodeMCU, heat sensor, relay, fan, lcd display
2. Use a DC volt sensor and NodeMCU to send messages to my cell phone when my car battery is weak. That project used DC voltage senso, NodeMCU, IFTTT technology to get text msg to my cell phone.
3. Use switch and NodeMCU to send message to my cell phone when yard gate is opened and closed.
4. Used weight scale sensor with NodeMCU to weight items ranging from cotton ball to bowling ball.
5. Used Text-to-Speech module with NodeMCU to create a Voice Server so my various NodeMCU projects can use Wi-Fi to send messages to the Voice Server to speak.
6. Use temperature probe and NodeMCU to create a thermo logger that records temperature changes on a microSD memory card and can transmit the temperatures in a web page etc.
It is fun and fairly easy to create a variety of different types of smart switches using different sensors, relays and these NodeMCU ESP8266 chips.
I use them for monitoring various things such as a water alarm in the basement, sending a push notification when my 3D printer finishes, monitoring battery status of solar powered systems, for security, etc.

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.

I ordered a kit of three - the first two I happened to use work fine.
Yesterday I tried to flash ESPHome on the 3rd, however the product is dead.
Return & support dates have since passed.
Do I have any chance of getting a replacement or partial credit?
I am planning to order another kit of 3 of these.
Thanks for anyone with Amazon who cares to respond.
