Which NodeMCU should I buy?

We recommend the NodeMCU Kit or the WeMos D1 Mini because both boards have a built-in programmer chip, making it easy to upload code. Additionally, they also offer a reasonable number of GPIO pins. However, if you need a tiny board for your project and only need 2 GPIOs, the ESP-01 is a better and cheaper alternative.

What is the cost of NodeMCU?

Amica Node Mcu Esp8266 Development Board

Which NodeMCU ESP8266 is best?

Top 6 ESP8266 Modules for IoT Projects

• Adafruit Feather HUZZAH.
• NodeMCU Dev Kit.
• KNEWRON smartWIFI.
• SparkFun Thing.
• WeMos D1 mini.
• Wio Link.

What is NodeMCU V2 ESP8266?

NodeMcu is an open source IoT platform based on the ESP-12 module. The board is pre-loaded with LUA firmware that enable you to prototype your IoT product within a few Lua script lines. You can also program it using Arduino IDE.

Which is better Arduino or 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.

Which language is used in NodeMCU?

Lua scripting language
The firmware uses the Lua scripting language. The firmware is based on the eLua project, and built on the Espressif Non-OS SDK for ESP8266. It uses many open source projects, such as lua-cjson and SPIFFS.

Is NodeMCU better than Arduino?

What does NodeMCU stand for?

NodeMCU stands for Node MicroController Unit. The below image shows a NodeMCU microcontroller board. Image Source. According to this article, NodeMCU is an open-source Lua based firmware and development board specially targeted for IoT based applications.

Which is better NodeMCU or Arduino?

Is NodeMCU good for IoT?

NodeMCU is based on the Esperessif ESP8266-12E WiFi System-On-Chip, loaded with an open-source, Lua-based firmware. it’s perfect for IoT applications, and other situations where wireless connectivity is required.

What is the purpose of NodeMCU?

Overview. NodeMCU is an open source firmware for which open source prototyping board designs are available. The name “NodeMCU” combines “node” and “MCU” (micro-controller unit).

Can we replace Arduino with NodeMCU?

Well, the answer of the question “Can it replace Arduino” – yes, in many cases it can.

Can a Lua script work with NodeMCU firmware?

If you want to work with Lua Scripts and NodeMCU, then you have to flash the NodeMCU Firmware. As mentioned earlier, the NodeMCU Devkit is actually a Breakout Board for the ESP-12E Module. The ESP-01 is the vanilla version of the ESP8266 Wi-Fi SoC made by Ai–Thinker, a third part module manufacturer for ESP8266.

Which is the best way to get started with NodeMCU?

The Getting Started with NodeMCU is not complete until you upload the Blinky Sketch using Arduino IDE. So, let us proceed with configuring Arduino IDE. If you worked on ESP-01 Module or other ESP8266 based boards, the you probably completed the initial setup in Arduino IDE. But none the less, let me explain the steps once again.

What kind of breakout board does NodeMCU use?

As mentioned earlier, the NodeMCU Devkit is actually a Breakout Board for the ESP-12E Module. The ESP-01 is the vanilla version of the ESP8266 Wi-Fi SoC made by Ai–Thinker, a third part module manufacturer for ESP8266. Pinout of ESP-01 Module In fact, the modules produced by Ai–Thinker are one of the widely used in other ESP8266 boards.

What kind of programming language does NodeMCU use?

Technically speaking NodeMCU is a firmware for ESP8266 developed using C Programming Language, Espressif NON-OS SDK and Lua scripting language. Traditionally, we write code for our Microcontrollers like Arduino, STM32, 8051 etc., either in C or C++ and compile it with a set of tools and generate a binary file.
