I bought 3 of these to add to my inventory for future projects. PROS: They arrived earlier than the estimated delivery date. I tested all 3 with a script I had used before (read the A0 and send it to a server over WiFi). All 3 loaded and ran flawlessly. Good price. CONS: Only one. These are wider than a unit I purchased from another vender, It barely fits on a wireless breadboard. it reaches to the last rows on both sides of the breadboard (not the power rails). I had to use risers on the module and run the jumpers underneath it.

The price is affordable, but this isn't the one you want. This is a NodeMCU v0.9 which won't leave you any room on a breadboard. It covers all of the holes in the breadboard so you can't plug in any jumper wires. The newer NodeMCU v1.0 is narrower and allows access to the breadboard connections. Additionally, I couldn't get this to connect to my computer. I installed USB drivers and everything, but perhaps I my USB cable is bad.

This is a very good quality product. I have purchased the ESP32 and two of these ESP8266 development boards. This board contains the USB/Serial programming interface, the 3.3V regulator and of course the ESP8266. If you plan on powering this using your own 3.7V Lipo battery or other means, you would connect directly to the 3.3V pin. Lipo batteries are 4.2V when fully charged, so this will damage the chip. You will need to provide your own external regulator. The built-in regulator is designed for 5V input via the USB cable and will not function properly with only a 3.7V Lipo battery. The ESP8266 is designed to "sleep" at a minimal 20ua (microamp) current draw. It does that, but the other components on the board still draw current. A running board online with WiFi is around 70-100ma (depending on what else is on it), and when sleeping, it runs at around 3ma, not 20ua. You can buy a separate ESP8266 and a separate USB/serial board. There are also development boards specifically designed for 3.7V Lipo battery power. I'm mentioning all of this because this development board is convenient, but may not be the correct board for all purposes, especially Lipo and/or solar powered projects.Read full review

Pros - Works as expected. Inbuilt 3.3v really helps ! Small enough for PCB implementations. Cons - Only problem I see is its not breadboard friendly. It takes the whole breadboard and does not leave any hole for to plug in external wires. I can only work with it using jumper wires attached directly to the pins. Two breadboards can also be used together to fit it and leave space for the wires on each side, but I have not tried it.

Works as expected, but it's so wide it barely fits in a breadboard. It looks like the only way to easily work with this board is to buy the breakout board specifically made for this device. They're also inexpensive. Or, maybe you could cross over two parallel breadboards instead? Hard to say.
