What is the difference between NodeMCU V2 and V3?
Turns out that V3 is a “version” invented by producer LoLin to signify minor improvements to the V2 boards. Among others they claim their USB port to be more robust. If you compare the pin layout there’s only a tiny difference to the V2 layout.
What is the difference between ESP8266 and NodeMCU?
ESP8266 is a microcontroller with WiFi capability. it requires external flash memory and some antenna to work. The NodeMcu firmware is a Lua language interpreter and has nothing to do with Arduino, but the NodeMcu development board can be used as any other esp8266 development board.
What is Ch340 NodeMCU?
The NodeMCU V3 is a breadboard-friendly open-source ESP8266 development kit, armed with the CH340G USB-TTL Serial chip. The CH340 line of chips is notoriously known as the affordable alternative to the CP210x.
Which node MCU is better?

What is ESP8266 12E?
Esp-12E Esp8266 Wifi Module is a low power consumption of the UART-Wifi module and ultra low power consumption technology, designed especially for mobile devices and IoT applications,user’s physical device can be connected to a Wifi wireless network, internet or intranet communication and networking capabilities.
Can ESP8266 replace Arduino?
4 Answers. Well, the answer of the question “Can it replace Arduino” – yes, in many cases it can.
Is Arduino better than NodeMCU?
In common the NODEMCU is based on the ESP8266 microprocessor have a very low current consumption between 15 µA and 400 mA which can be further decreased with the deep sleep mode activated to 0.5 µA. The current consumption is then a factor 70000 higher in deep sleep mode for the Arduino Uno with 35 mA.
What is ESP 12E module?
ESP-12E is a miniature Wi-Fi module present in the market and is used for establishing a wireless network connection for microcontroller or processor. It features ability to embed Wi-Fi capabilities to systems or to function as a standalone application. It is a low cost solution for developing IoT applications.
Can NodeMCU replace Arduino?
Well, the answer of the question “Can it replace Arduino” – yes, in many cases it can.
Which is the best CH340G or CP2102?
CH340G is the Chinese one. CP2102 is Silicon Labs. Good win driver support. It is also important that they work with 5V and 3.3V UART signaling.
Which is FT232RL CH340G CP2102 which to choose?
Those boards are based on chips FT232RL CH340G CP2102 and others. CH340G is the Chinese one. CP2102 is Silicon Labs. Good win driver support. It is also important that they work with 5V and 3.3V UART signaling. Also it would be good if I could use it in other projects as well.
Is the CH340 a good choice for Windows?
So perhaps the CH340 is not a bad choice for Windows. There are even CH340 dongles which support SPI mode 0 and I2C in addition to UART, although some special software is required to use that functionality. IIRC the CH340 can be switched to either 3.3V or 5V and some boards provide a jumper.
Is the CP2102 a 3.3V device?
The CP2102 is a 3.3V device, and its Tx, DTR, and RTS outputs are 3.3V. I think in most cases 3.3V would be read as high in a 5V system, so they probably would work, but technically not a match.
