It work great if you not intend to use in breadboard and their low quality fake regulator should able to handle <11v with okay performance.A USB adapter is a type of protocol converter that is used for converting USB data signals to and from other communications standards.

Jin Maker suggestion: This is usually the lowest cost NodeMCU you can find. The earlier Lolin revision doesn’t have this build in.

This mean the ADC voltage input can go from 0–3.3V rather than the other nodemcu 0–1v only. The reason why I say this is the newer revision is the additional of voltage divider resistor on the A0 pin.This come very handy in powering 5v sensor as their data pin usually 3.3v tolerance to ESP8266. Please keep it mind there is no 5V regulator onboard so you getting non regulated 5v power from the USB itself. One of key improvement Lolin did is route the 5V power from USB power to a new pin (beside A0, lower right), which solve the problem that NodeMCU doesn’t have a 5V power output.As component price increase in china, Lolin design a new board layout (Big board -> cover the whole breadboard) for NodeMCU that use lower cost component that use bigger footprint (easier to pick n place and rework fail unit).They stop making NodeMCU so the board out there is mostly just china clone. Lolin then rename themselves as Wemos and make a new board design which I love -> Wemos D1 mini. This is actually the newer revision of Lolin design.4th one from the left: Lolin CH340G NodeMCU Avoid this if unless you just use it for fun. There is also high chance it use a fake AMS1117 regulator so avoid supply more than 10v to the VIN to power this. It use lower quality component there is very high risk it get brown out if you didn’t provided proper 5V voltage. This is just the component reduced and cost down version of the previous module. (Cheaper and more reliable if you buy from their official store) 3rd from the left: Cost down CH340G NodeMCU (Amica clone) But i will just use Wemos D1 Mini anyway for breadboard friendly board. Provided you can find this board and the manufacturer did make this board nicely and fully tested it. Jin Maker Suggestion: IF there is actual need for NodeMCU smaller board, this is the best choice.

This use CH340G so not suitable for school PC as they usually don’t have admin right to install CH340G driver.

If I have need to use a smaller board in NodeMCU pinout, I will go for this. Hence require a more precise pick and place machine and it use yellow Tantalum capacitor.

Aim to replicate the same size of Amica NodeMCU, it pack a lot of component together. This is actually the better variant of the CH340G NodeMCU.2nd from the left: CH340G NodeMCU (Small board) Most of them don’t use original CP2102 chip anyway so there is no real advantage. Is hard to find this version and mostly old stock or more expensive than other. The good thing is, the board size is smaller to fit in breadboard and leave a spot for header pin to plug in.However, the ESP module is original Ai-Thinker ESP-12E/F module. Most of the CP2102 chip from china is fake with no visible marking. As Amica is gone (founder was just a student that time), the official board is no longer available. This is the clone of Amica the original creator of Nodemcu.1st from the Left: Fake CP2102 NodeMCU (Amica clone)
